    Just did mine today and had the same issue with the reg plates and the side lights. Went to halfords and paid 11.99 for a fuse kit.

    The fuses your looking for is In the fuse box to the right of the battery. They are upside down.

    F6 is for the reg plates and f7 is for the side lights. Look at both fuses just in case I have it the other way around.

    I went through 6 fuses before getting it right. For mine the leds would blow if they were the wrong way around. They were also causing a little hassle with the left vs the right side of the car. As in i had an led that would work at all in the right but worked fine on the left.

    Got a 10 pack of 10A mini fuses in Halfords for €6.50 at lunchtime there, so gonna have a cut off things when I get home.
    Also got my home charger and installation ordered.

    This car is making me super efficient! ;)

    Hi
    I've been following this thread a while and decided to take a test drive in a 30kw SV leaf today. Was pretty impressed alright. Ok on the road and nice acceleration. What surprised me was the space inside especially the boot. Didn't expect that. However, not impressed with forking out extra for fast charger and granny lead. No scrappage either for the time being. Garage has a 24 KW 161 with 3k on clock coming in next week. Anyone able to give a ballpoint figure for this as salesman unable to provide any number? Thanks

    Look at similar cars with such low miles in the uk. Convert price to euro. Add 2k to the figure and you'll be fairly neat in the ball park.

    You can bring in a 30kWh 161 from the UK for about €17k landed, so a good few thousand less than that would be your answer, maybe €14k from a main dealer. That is what it is worth, but no doubt the Nissan dealer would want more for it.

    FYI I was looking at buying a brand new 24kWh Leaf last year and with the fast charger and metallic paint I got a price of €20k cash on the road. 24kWh Leaf is now obsolete so I would negotiate hard. Some dealers are realistic and will play ball. Others still think in terms of "what it stands me" and they are wasting your time and their own time

    Good luck and keep us updated!

    Was at the fast charger this evening and there was a Leaf plugged in and fully charged, but the owner could not disconnect the CHAdeMO cable. When I got there he had already spoken to the eCars crowd (number on the charger), but there was no resolution yet. We both agreed that if I plugged the CCS into my car, it might disconnect him. I connected, mine started charging straight away, but did not disconnect him

    Felt sorry for the owner, as it is a crap situation to be in. Nothing I could do to help him though, when I came back to my car a few minutes later he had left (leaving his car there)

    For future reference - so I could maybe help someone if I came across this situation again - has any of you Leaf owners had this and what way was it resolved?

    Yes. I was stuck at a FCP in the UK. Car started charging (for free...another fault). Ecotricity had closed for the evening. I hit the big red button and disconnected the cable. It's the only way.

    Kinda.

    Reg plate bulbs were a doddle.
    One of the side lights were faulty. No matter what way I put it in, or on which side, it blew the fuse. Went through 7 of them! Contacted the seller and he's sending me on a replacement.
    The last one is my own fault. I though the DRL LEDs would replace the fog lights, but they don't! Waste of 20 minutes trying to get them changed.

    So if anyone want a couple of LED replacements for their DRLs, give us a shout. Will let them go cheap! ;)

    Had my first fright this evening. Range dropped to 11kms and one bar left, with the low charge warning on the dash. Got to the fast charger, plugged it in, and the charger told me there was 21% charge left in the battery!
    So how far could I push it? Does it die at 0%? 5%?
    Trying to suss it out.

    What does the big red button do? Apart from disconnect you? Will the whole charger stop working until someone from ecars resets it, or even need a site inspection?

    Shuts it down and reboots the system. Should in theory power back up and function by itself.

    I found some of the chademo handles very flimsy and the lever broken and I've had a few occasions where I had to apply some pressure to remove it, this was after the charging had stopped.

    .

    What went wrong?
    The DRL and the fog bulbs are 2 separate bulbs.

    The fogs are H11 and the DRL's are P13 bulbs. The 2 bulbs are located in the same light unit. The DRL bulb is the lower on that kinda points up.

    ''Tis weird.
    Those bulbs are there, but aren't working or don't seem to be connected.
    There was also what looked like a spare connection point for a bulb next to the foglight connection. It was into this that the DRL LED fit into perfectly, but there was no power to it when I turned on the lights.

    Ah well.


  • Registered Users, Registered Users 2 Posts: 6,638 ✭✭✭zilog_jones


    Are you saying the DRL bulbs are present but don't work? Not sure about the Leaf, but in my Prius the DRLs won't turn on if you start the car with the parking brake on - you need to disengage the parking brake.

    There are 2 bulbs in each casing. One is definitely the foglight, and turns on when you turn on the foglight.
    The other one points upwards as described by kceire.
    When I took out the foglight, there was a second connection on the same loom with nothing connected. It was actually into this that the DRL replacement bulbs fit perfectly. They never turned on though.
    But now that you mention it, I never tried put the car into drive. So maybe that would've turned them on? That said, there doesn't seem to be a fuse for them either.
    Annoyed I didn't think of putting the car in drive. :mad:


  • Registered Users, Registered Users 2 Posts: 8,295 ✭✭✭n97 mini


    When power is on the DRLs come on. No need to put it in D.

    I meant disengaging the parking brake (I'm not saying "handbrake" because it's operated by a pedal ;) ), not taking the transmission out of "P" which is a different thing. No need to put it in drive.

    If you don't use the parking brake, the DRLs will come on when you start the car.

    Again not certain with the Leaf as I can't find the manual online, but seems like a fairly common setup in other automatic cars (incl. other Nissans).

    DRLs were only made mandatory on cars type approved after 7th February 2011 in the EU - I'm not sure if this means that if the model was type approved before that date (which the Leaf probably was) then they were not required.

    If they're not working, it's possible the wiring is there and they just need to be enabled via some OBD-II command.


  • Registered Users, Registered Users 2 Posts: 21,808 ✭✭✭✭Water John


    Zilog, even to say 'when you start the car' sounds strange on an EV. When you 'power on' those lights come on.
    Not trying to be a smart ass. We just need to develop a commonly accepted terminology for EV driving, so that we don't misunderstand each other.

    You are right about 'handbrake', when it's a foot brake, parking brake means what it says.

    Following on from my post 353...

    Can someone tell me which fuse is for the drl? Since it seems like the wiring is already there, I'm wondering if it's just missing the fuse to complete the circuit?


  • Registered Users, Registered Users 2 Posts: 6,638 ✭✭✭zilog_jones


    I'd suspect it's more likely to be a software controlled thing, and since it's just two 13W (?) bulbs I doubt they're on a separate circuit.


  • Registered Users, Registered Users 2 Posts: 8,926 ✭✭✭Soarer


    Well the front fogs have their own fuse, so why wouldn't the DRLs?


  • Registered Users, Registered Users 2 Posts: 6,638 ✭✭✭zilog_jones


    Actually they might do, and it may be a requirement for the EU type approval stuff. It's a 7.5A fuse in my Prius.

    Do you not have the owner's handbook? That should have a detailed description of the fuses.


  • Registered Users, Registered Users 2 Posts: 8,926 ✭✭✭Soarer


    I do, and it doesn't from what I can tell.

    Maybe I'll just throw the bulb into the socket, and pop a fuse into all the open spots in the fuse box to see if anything happens.


  • Registered Users, Registered Users 2 Posts: 12,460 ✭✭✭✭DrPhilG


    I bought one of these bulb kits but after all this talk of blown fuses I don't know if I'll chance it!


  • Registered Users, Registered Users 2 Posts: 8,926 ✭✭✭Soarer


    Tis the same fuse that blows everytime. F6.

    A pack of 10no. 10A mini fuses are £4.39 in Halfords UK or €6.69 in Halfords Ireland.

    Do it DrPhil, do it!!!

    The original chademo plugs (with a big lever and button on the top to release) also require the button pressed when removing from the car. Not just for releasing the lever. Took me while to figure out why they were sometimes difficult to pull out.

    Luckily they are getting replaced with the newer type with a sliding release button.

    Will the SCP charge to 100% if you leave it long enough, or will it stop at 80 or 90%, and you have to restart it? Is there a setting somewhere in the Leaf that has to be switched off?

    Going to use the SCP for the first time this evening, and leave the car for an hour or two. But I don't want to come back with it after switching off before 100%.

    It will charge fully and balance if you leave it long enough without stopping. It won't charge if you have night rate settings on so remember to turn those off. Only fast chargers ignore those settings.

  • Registered Users, Registered Users 2 Posts: 4,721 ✭✭✭Balmed Out


    Few more questions if people would be so kind,

    When plugging in / out does it matter if you plug in the car side or the charger side first?

    Charging to 80%, is that actually best practice or not. I know newer leaf's in US at least dont have the option as nissan considered it didnt matter and that there is already a buffer ie. we dont use the full 24kw's.

    That charge timer button on the right, should it light when pressed?. Mine doesnt and I'm not convinced yet it actually works. I seem to need to turn off the charge timer settings from the display panel except at a fast charger where it doesnt seem to matter.

    For a 24kw leaf am I doing ok or very poorly to be using 43% of battery on a 60km journey (would work out to about 112km @80% or 139 @100% ) - normally at speed limit unless traffic?

    I seem to be the only one who puts the rubber head back on the charge point at a local fast charger, presumably I should continue to do so?

    oh I forgot, the buffeting noise / helmholtz ressonance. Anything that can be done. In other cars I have only heard it when a back window is down but in the leaf I can hear it when driving at speed and no window is down. This is possibly due to my poor hearing where I seem to hear things others may not while being tone deaf and needing to be looking at someone to definitely hear what they say.

    No. I tend to plug the socket in first, then the car if using a scp or granny cable, but that's just habit.

    If you're not going to use the car for a few days, charging to 80% may be beneficial. Otherwise, go 100.

    I haven't seen mine light up. if I am charging at home and the timer needs to be turned off, I open the flap first, then I press the timer button and it all works fine. You could also open the flap, plug the car in and then press the timer. That works too. If the dash light are intermittently flashing on and off one at a time, the timer is still on. If there is just one light flashing, you're charging. Of course, one or two of the other lights may stay on too. This reflects the state of charge.

    Just to add, IIRC, when you press the override timer button the center light of the 3 blue lights should be on and the other two off. That indicates its ready to start charging as soon as it senses an EVSE connected.

    I believe the override button wont do anything until you power the car off. Thats the only thing you need to do before pressing it. It doesnt matter if the flap is open or cables are or are not connected.

    And the timer is only for AC. The timers and the override button have no effect when charging DC.


  • Registered Users, Registered Users 2 Posts: 21,808 ✭✭✭✭Water John


    On one of the other threads, someone said car first always, both connecting and disconnecting.

    Found it, from Fiery Mutant

    When I was getting the charge point installed at home, the guy doing the install said 'always plug the car first, then the point. Same when taking out, always the car first, then the point.'

    How to read the charts from LeafSpy? What to look for?

    All you need to know is here:
    http://www.electricvehiclewiki.com/Leaf_Spy_Pro#Screen_1

    The state of health % or the Ahr figures are the important ones. That gives some indication of when you are likely to lose a health bar.

    Its also good to run the car to very low battery warning and then look at leafspy as it will then tell you if all the cells are ok or not at the bottom of the screen.

    If you are looking to buy a Leaf another thing to look at in LeafSpy is the number of quick charges(i.e. rapid). Lower the better.

    Bear in mind , at least for the current gen 24 Kwh Leaf the reported AH and Health can vary.

    For instance, if I leave the leaf sit with little use on my days off shift I can see the reported figures drop, say it reports one day I've 65 Ah (which was the reported capacity brand new) and a few days idle can see 61 Ah being reported.

    The Health can also vary from 100% to 91%. So I wouldn't read too much into it. The health shows the internal resistance which represents an overall condition of battery health, as it ages it's internal resistance grows and makes it harder for all the electrons to move around causing increased heating and greater voltage dips when a high load is applied ( harder acceleration and fast charging or regen braking) .

    When the battery has lost a few bars it won't be able to fast charge at the same level of power and regen won't provide all 30 Kw as has been observed in the original battery that suffered far greater capacity loss than the current gen 24 Kwh Leaf battery. What's happening now is that it's a lot harder for energy to get in and out of the battery and on top of that the batter can't store as much energy due to capacity loss.

    The GOM may show you have xx kms but when driving because the battery is under more stress it can't deliver the same level of power due to the voltage dips when under load so the GOM will end up reducing it's reported Kms as you drive because the BMS will think that due to the voltage dips there is less energy in the battery than there is it's just the battery can't get the energy out as fast now due to the greater internal resistance and so the voltage of the cells drops.

    The GOM will vary anyway as you drive due to changes in terrain etc , the same principle applies here, if you're now climbing a long steep hill for instance the voltage will drop under load and the GOM will report less available Kms but, in the updated Gen Leaf you have a battery % reading, and this won't drop like the GOM and so most people learn over time on average how many Kms they will get per % of battery.

    Improvements in battery tech will mean that you can get many more kms before all this happens such as in the current Gen 24 Kwh Leaf.

    Only while the battery does not get frequently near the red. The current model 24 Kwh Leaf only allows 45 Kw charging until only about 50% charge. But multiple fast charging in a day can cause it to heat up near the red.

    The 30 Kwh heats up faster probably due to the fact it allows 45 Kw all the way to 80%. The effects of this are unknown yet but indications in the U.S suggest it suffers the same level of degradation as the current 24 Kwh in hot environments so with the 30 Kwh you might need to be a bit more cautious if it's getting hotter on the fast charger.

    None of these effects become known for some time so it's good to be more careful if you intend to keep it long term.

    A U.K taxi had covered 100,000 miles and lost something like 9% battery with a huge amount of fast charges, I'll see if I can dig up the article. But this is an amazing improvement compared to the original battery which could see 1 bar lost by 80,000 kms and half the amount of fast charges this taxi had.

    The L2 charges are counted x 2 due to a firmware bug, I don't know if this has been fixed. So I think it's safe to assume that for a 24 Kwh Leaf you can half the amount of L2 charges that leaf spy reports.

    No the Leaf manual does not say it's irrelevant at all. It's just a lot less relevant than it was on the original leaf battery.

    Couple of factors "could" be involved, improved cycle life , heat resistance and "C" capability, C being the amount of current it can take in and out and/or a combination of them all. Just small changes can have a huge impact.

    For instance , if you have a 10 Ah battery with a 1C discharge and 0.5 C charge rating then it should not charge at more than 5 amps and discharge at more than 10 amps.

    A 2 C discharge and 1C charge rate means it should not discharge at more than 20 Amps and charge at more than 10 amps and so on.

    Purely from an engineering design background perspective, I would suggest it being good practice even if the blurb says its "no longer an issue".
    No " proof" being offered, just an opinion.
    Fast charge is a bit like wham bam thanks mam

    There are a few studies on this, one in the UK that I can't find link to at present and another in the US https://avt.inl.gov/sites/default/files/pdf/vehiclebatteries/FastChargeEffects.pdf

    The impact on Battery from using Fast Charging is very little but this myth still seems to be flying around the place and like above usually without proof

    I think the only concern with rapid charging is the higher risk of heat damage. I think it is generally accepted that heat is a battery killer and several rapid charges in one day will take the temp to the "red" zone. If that is done regularly then the battery could be affected. If you never overheat the battery then the rapid charge probably has no discernible effect.

    Looking at LeafSpy and seeing alot of rapid charges wont tell you if the battery got hot but a degraded battery along with a lot of rapid charges would be things to look for when buying second hand.

    Its not an exact science of course, nor is buying an ICE!

    Can't see it being an issue in Ireland tbh

    What exactly?

    Its relatively easy to put the battery in the red in Ireland. 2 or 3 rapid charges and you are there.

    On the 30kw version maybe.

    I drove from Cork to Donegal via Dublin with probably 7 FCPs en route and only hit the high temp zone at Monaghan which I think was my 6th charge.

    Its harder to do on the 24kWh alright. Mine went to temp bar 9 after 4 rapid charges when I brought it back from the UK(<10C at the time) and was doing an indicated 75mph most of the way. So, you have to push it hard to make it happen on a 24kWh.

    It would happen faster if it was in the summer and the battery was warm to start with.


    The 30kWh seems to be much easier to hit red due to its faster charge speed. Maybe 2 rapids?

    Because we don't have that many FCPs and our climate is isn't warm so the number of cars that would be doing enough FCPs in a short space of time to do that would be very very small imo.

    I'm not saying it can't be done but the whole myth about FCP charging making a big impact on battery performance is exactly that, a myth and there are proper studies to show it.
