Ok so I've been messing with this H4 conversion and i'm about to toss it but I'm so close its not even funny. I had the high beams working and then started on the low beams and did them one by one. Everything seemed to work fine. Then I put everything back together and went to turn the things on and NOTHING worked. I can hear the low beam relay click on and off but no the high beam relay and the turn signal lights and side marker lights that usually come on with the headlights aren't coming on either. I checked the fuses for them and it was fine. I'm not blowing any fuses but i'm not getting power to ANY of the lights on the front of my car. Could it be the circuit breaker in the light switch? i cant seem to find any breaker so the location of that would help. Thanks in advance.

 

The headlight switch is designed to handle the load of the headlights. Double check your grounds and go slowly over everything. Also, a bad high beam switch will cause no headlights. Not sure if this is part of your wiring though. I have never instaled a headlight conversiton kit.

 

I dont think its the high beam switch...the blue high beam indicator comes on when i flip the switch and i can hear the relay get triggered. I'm guessing there is a bad ground somehere....GREAT!
