Right hand low beam is not working

Hi,

I attached the entire wiring schematic for the headlamp system. I had to cut the pic in half to make it readable, but I did overlap them.

I need you to first look at pic 1. It shows the fuse box under the hood. Confirm the highlighted fuse is the one you checked. If it is, then I need you to confirm there is power both to it and from it. Here is a link that shows how it is done:

Now, I have a question for you. You indicated there was power to the ground wire but not the power supply wire. You shouldn't have power to the ground. Please confirm that the black wire doesn't provide power. You should only have continuity to ground via the black wire. The yellow wire should have power (12v). Here is a link you may find helpful:

Now, if you have power from the fuse I highlighted and it isn't at the connector, there has to be an open in the wire (damaged or shorted).

Do these checks and let me know what you find.

Take care,
Joe

Hi,

The best thing to do is start at the light socket. Make sure there isn't damage there. If I was doing it, I would simply connect to the power supply wire and start moving the wiring around to see if you get power at any point. It could be anywhere. However, if you have power out from the fuse, there is a disconnection at some point.

Wiring can be difficult. If your test light can pierce the wire's insulation, start at the fuse and follow it until you lose power. Then you will know approximately where the problem is located.

I hope this helps. Let me know if you have other questions and what you find.

Take care,
Joe
