Head light and tail light not functioning

Hi,

The wiring schematics are broken into two sections, headlamps and exterior lighting. The rear tail lamp issue will be under exterior lighting. The headlamp will be under headlamp.

Pics 1 and 2 are for the headlamp. I cut the pic in half to make it more readable. I did, however, overlap them so you can follow it.


Pics 3, 4, 5, and 6 are the exterior lighting schematics. Again, I cut them in half to make it more readable, and I overlapped them as well.

I hope this helps. Let me know if you have other questions. If you have a chance, let me know what you find.

Take care and God Bless,

Sir, considering the 2nd diagram, it seems that the H-LP relay has no function since the circuit is ground by switch, am I right? If I am what is the function of the relay?

How does the high beam indicator work since it is connected to the ground of both switch?

The relay gets ground at the left front fender.

What I am saying is that the whether the relay ground or not it won't stop the headlights from coming on.

If the relay doesn't have ground, it will prevent the light from working. No power will be transmitted through the relay.

Thank you.

Hi,

No problem. Let me know what you find.

Take care,
