I have been trying to figure this battery light problem out forever and some have probably already seen my other posts but nothing has worked. I haven't fully got all my battery cables upgraded to higher gauge yet. I had replaced all cables with new Jaguar cables and put in a new alternator and also just replaced the battery. I am noticing though that my passenger airbag may not be working correctly. If I am correct, when it is lit up it is not on. It seems when the airbag light is lit correctly this seems to be the times my battery light is off. I bought this car from a Jaguar dealer and carfax has nothing about a wreck. That is my main question but I have one other thing I would like to ask. Does anyone know what the reset button with a gas pump on the passenger side kick panel does? Just curious. Your help is very appreciated. I'm one of those people that the problem will bother me till I get it solved.
