Thread: Charging system failure w/HID's

Each bulb is suppost to be 55 watts. So 55 x 6 = 330 watts. And that is with them all on which is actually not possible. 330 wats divided by 12 volts( should be 14.4 but will do 12 since gives more room for error). That equals 27.5 amps total. Each set is on a 10 amp fuse and none have blown. The 10 guage wire will handle the 27 amps no problem. There is no way of testing inrush voltage or amperage on the ballasts for when they first turn on. Even my high end flukemeters miss that inrush. i thought about borrowing a fluke osiloscope logging meter to see exactly what is going on. May be over kill though.
