Question on Jump Starting

    I have a car that needs jump starting, I have the leads, I'm well used to doing the whole thing, but it's always been on cars of similar size, and I understand that the two cars shouldn't be too different on size.

    However I want to jump start a 1.6 petrol car, and I can easily do so from either my own 2.2 diesel or my girlfriend's 1.0 petrol. Which one, if any, is more suitable? Or should I just ask my mate with the 1.8 petrol?

    Doubt it makes a difference but jump the 1.6 off the 2.2 as it'll have a stronger battery.. good luck.

    I think if you have to jump start a diesel it might be tricky without the right leads?

    But you are jumping a petrol motor which is small enough so it should be fine. I've jump started a 1.8 from a 1.0l polo. Both petrol.

    I remember there being leads for the van and leads for the car. They looked different :confused:

    i jump started my dads 2.4 camry using an old ford ka the other day. engine size makes no difference imo.

    I never heard of this problem jumping another car.
    As long as the batteries are 12V it should be fine.

    If you have the choice - use the bigger engine's battery. Trying to start a big diesel with a small 1.0l petrol car's battery can permanently damage the battery.

    The best thing to do when jump starting are the following:
    1. Use a decent set of leads, do not use a €20 set as they are potentially going to cause problems.
    2. Leave the donor car engine running for a few minutes while the leads are connected the car with dead battery. If you hold the accelerator at just slighlty above tickover it helps charge the battery.
    3. Do not attempt to start the dead car straight away, give it a chance to charge a bit first.
    4. Connect the positive lead up first & disconnect last. Connect the negative lead to negative terminal of dead battery & to a suitable earth point on donor car, I have always been told to avoid the actual negative terminal.
    5. Avoid jump starting if at all possible, there are so many electronic control units in cars today for engine management, central locking, etc. The potential damage you could do to these units in either connected car could turn out to be quite expensive.
    A few ways to reduce potential cost of damage while jumpering:
    1. Buy a jump start pack, again get a decent one for about €150
    2. Replace a failing battery as soon as possible to reduce the amount of times you are jumping a car.
    3. For cars that are parked up for long periods without being started invest in a trickle charge unit & connect up to a disconnected battery every week or so.
