does anybody know what voltage the electric accessories operate on a 2002 TL? i have them hooked up correctly to my EG hatch, but AF gauge goes weird when i turn them on, then when they are on and other electric stuff is on in the car the af gauge jumps again, could it be a bad alternator, or that im running my MSD and the HID's off the battery?? do i need a dry cell battery to handle the extra stuff??? the input volts on the ballasts say 13.5 v, i know civics run on 12 volts, is this a problem?????? thanks
