    Yes it will pass as there is no provision in the testing manual to fail for this defect

    Good God is there not? Surely a safety issue? Battery not charging / holding charge, powers electrical systems, electric power steering, ABS control units etc can surely cause an accident if one system suddenly fails due to low voltage.

    More power to the OP if it passes, but I scratch my head about who actually wrote that NCT manual in the first place....

    I wouldn't be so alarmist about it but yes maybe something the RSA should consider about adding in ( as they are the ones responsible for the testing manual ) . The manual is old and tired at this stage ... it is a slight adaption of ye olde DOE manual so it wouldn't be any harm to re-write some areas specifically for todays vehicles and maybe clarify some testing procedures too..

    "But the batteries do be do not charging Joe. think of the children"

    there are separate ABS sensors that will alert (and you will fail NCT on that)

    If the car can actually start on the battery there will be enough power for the lights, steering etc.

    ABS, ESP, airbags and on some cars the power steering will not work correctly if the voltage is not in the proper range, which is something that is very likely to occur soon if the problem is not fixed. Also, a broken alternator may overheat and become a fire hazard. So even if it's not a safety issue by the NCT manual, it should be.

    if the voltage is that low, no chance the battery will be able to start the car in the first place.

    Again, it's not that low now, but it's lower than it supposed to be (or even worse, higher), and it won't get any better. A car with a malfunctioning electrical system is a safety hazard.

    I feel that alarmist is the best way... I must be used to customers throwing alarmist at me "you didn't replace the interior bulb on the service so I had to turn on my phone and blinded the oncoming traffic at night and I could have crashed and kill 55 people....and it's all your fault..." etc

    Thanks everyone. It can confirm it did NOT fail on the battery light.

    It failed on a bunch of other stuff though!
