mkay so the dealer says the alternator is fine: "there is nothing wrong with it from the tests, but if you need to upgrade then thats your call".
so anyways. after the initial flashing goes on (which doesn't always happen now?) the lights hold fine and there appears to be nothing wrong .. until you drive for a little, then the passenger side light flashes a little bit, not like on and off but brighter and dimmer.
i pulled into a parking lot, decided what the hell, and swapped the 35W amps to each HID. so
start -
headlight A headlight B
amp A amp B
new setup -
headlight A headlight B
amp B amp A
this seemed to solve the problem. almost. the passenger light started to flash again but not as frequenty, and this also proved that the amps weren't faulty as the drivers light stayed the same.
so anyways. next test is a multimeter reading of the passenger low beam plug compared to the drivers side. to see if the problem starts there.
