Troubleshooting electrical issue
Hi,
02 F150 4.6L
I have two aftermarket driving lights installed. They are grounded. Their power wires go to a relay. A wire from a head goes to a relay. A wire from the battery goes to a relay. The relay itself is grounded. Four wires total.
You turn on normal headlights and these lights come on. Off - off. They worked until I did this:
The wires described above were too long. I decided to shorten them and shortened them by cutting pieces out, removing insulation, and putting the two bared wire ends into a small metal "tube" and crimping it down (that's what it's meant for).
RESULT:
Passenger-side driving light works, driver's side light doesn't. BOTH normal headlights work.
The lights are grounded. Their two "power" wires are eventually combined into one, which goes to the relay. It gets power because one of them works.
The relay gets power because one of the lights works.
The relay gets a signal from the headlight because one of the lights works.
Lightbulbs are fine.
What is the problem? Where can I find what the problem is? Can the problem be that I shortened the wires and there is more juices reaching them? Reaching the relay? (power wire was only shorned by about 5 inches max. others by a few feet).

sounds like a bad connection. either you made a bad crimp, pulled a wire out of crimp or rewired it incorrect. recheck your wires. You did tape or insulate the crimp?
The length of wire has no real effect of the operation of the lights.
And next time try posting in the correct forum. Electrical.

Yeah, I agree. The crimp connection for the drivers side driving lamp must not be secure. You can test it with a multimeter, but I suspect that you'll have success by re-splicing the wires.

The wires that go from the lights are spliced into ONE wire, and that ONE wire goes to the relay. I haven't ****ed with those wires AT ALL... they go and become ONE... and AFTER they become one, THATS when I shortened and crimped it.... but one wire works and the other doesn't... So I don't think it's a poor crimping or anything.
