Is he running his ballast directly off the factory head light wire harness? Or is he running them through a 30 amp relay? Some HID ballast's require a pretty large current draw in start up. Not sure if this is the case with your friends HID set up, but you may want to check. If he is running them directly off the factory harness, I would recommend running them through a 30amp Bosch relay. Also he may want to check and see if he hooked his ground wire up to a factory ground location and disturbed a factory ground.

Just suggestions.

his kit is different then mine.. the ballast run straight from the factory wire harness but the lights are also tapped into the battery??? i dont know? there is a fuse between the battery and lights but i dont understand why its even plugged into the battery, mine arent. i dunno its really weird..

I have the plug-n-play HID setup like yours. No battery connections at all....connects stricktly to the factory headlamp plug. I have no idea why his would shut the engine off. Sorry I couldn't be of any help. Did he wire his that way on his own or does his setup require that kind of connection?

it requires it to be done that way... i think he should return it and get the plug and play application

Man, that sounds dangerous. I could just see him driving down the road at 70 mph, in traffic, he goes to turn the headlights on and pppfffttt...no steering, brakes, etc.:huh:

I had the same thing happen last year when it was cold, -20 F, but it went away. It has always been the drivers side light and it started again this fall. After a while it got worse and the drivers light would go out while I was driving over rough roads, no good. I bought some dielectric grease, loaded up the connections and taped the plugs together so they couldn't move, at all. The light has been perfect since, going on 2 months. We'll see when it gets really cold around here again.

I have custom Phillips HID kits for both High and Low beams. The factory headlight harness connects to the relays to control them. The power for the ballasts comes directly from the battery (via fuses of course) through the relay contacts. The problem I had is with the Daytime running lights sending reduced voltage (about 7vdc) to the relays on the high beams. This would cause intermittent operation as 7vdc is right at the threshold for energizing the coils on the relays. What I did to fix this is put resistors in series with the relay coils on my high beams. The resistors drop the voltage 2Vdc on the circuit. This way when the DRL's are trying to energize the high-beams with 7vdc the relay coils only see 5vdc and they will not energize as this is well below the threshold for energizing the coils. And when I want to use high beams the voltage is approx 12Vdc. The resistors still drop the 2vdc but now the relay coils see 10vdc and this is enough to consistently operate them. The resistor size depends on the coil resistance of your relay and should be at least 2watts for longevity. Not sure if this is a solution to your problems.

no reason for the engine to shut off. he wired something very very wrong!!


bring it to a shop before the ECU gets fried.
