Hey, folks

Trying to do a headlight upgrade with a relay harness I got from Amazon. That may be the first problem, but it was "redesigned" with more robust relays, blah blah blah....

Anyway, my headlight switch is working fine. I unplugged the new harness, plugged in one of the old bulbs, works fine. Plug in the harness, nothing. I've checked my wiring - orange plug goes to old headlight plug, blue plugs go to the new lights, red to battery + side, and black to ground. Cleaned the ground area with a wire brush, no paint, rust or dirt there. Inline fuse not blown. All electrical connections cleaned with DeOxit. Relays (one is 4 pin, one is 5) are in their correct places.

All I can figure is that the relays are bad. I hear no click when turning on lights. Marker lights and clearance lights work fine. New bulbs tested and working plugged into old plug.

Tomorrow I plan to hook the black to the negative battery post just to eliminate a bad ground problem.

Am I leaving anything out? I sometimes don't see what's right in front of me...any help is greatly appreciated! Thanks!

 

If you want to investigate any further, you will have to get a wiring diagram and start probing the new wiring with a testlight or voltmeter.

 

OK, self, be more thorough when diagnosing a problem. Don't run to FTE and bug people for answers when it was a bad crimp connection in the wire you had to extend.

Gee whiz. Sorry to waste y'all's time! I promise to be more methodical and thorough in the future!

 

I am glad you wrote back in with the fix. It's always something simple, it's just finding it.
