No continuity on override switch.

[chrger1967]

I was able to get the headlight doors to open today, but they won't close. I changed all the relays and limit switches. I pulled the override switch and cannot get continuity no matter what I try. Can I just add a jumper to this switch and see if the doors will close? And do I really need to spend over $100 on a new switch? It looks like a regular switch with a chrome knob.

Those are pretty easy to pull apart and clean. Could be the issue. But also could be an issue somewhere else in the system unless you know for sure they close and the switch is the issue

Looking at the schematic, when the override switch is "open" (no continuity) it's shown as off, when switch is "closed" ( continuity) it's shown as on. Should be able to check the switch with ohm meter by disconnecting the switch to check it's OK.

Yes you can simply jump/ tie the wires together and if everything else is good they should close when the headlight switch is off

I ran a jumper wire and they still didn’t close.

I’m not getting any continuity open or closed.

Easiest way I found was to work backwards. At the connector where the engine harness connects to the forward light harness, you can pull it apart and put 12v directly to the feed wires on the forward light harness side and see if they open and close. I think it’s the red and purple wires. I used my power probe but you could get it right off the battery. Easy/quick way you can see if the problem is up front or in the dash

If you don't have 12v on either wire to the override switch then the problem is further upstream.

So I should have 12 volts at each lead to that switch?

No just one it goes to ground on the other side.
It's the last thing in the circuit.

The instructions that came with the relays and the limit switches did mention it interrupts the ground for the doors to close. I will check for 12 volts tomorrow.
