Hi Lee;
I hope you don’t think I’m disrespecting you, but the process involves starting at the buss, and determining if voltage is present at the first stop, if it is, then go on to the next stop (component) to see if there’s voltage there, etc. until you get to the nav light receptacle.
If there’s no voltage at the wing tip, then go back in the wiring diagram and check for the presence of voltage at the last spot in the wiring scheme.
Does the tail nav light illuminate???
I ask because it looks like power to all three nav lights goes from the switch to a common spot, from where wires to all three nav light sockets branch from.
If the tail nav light isn’t lit, then there’s a problem between the switch and the common spot, or the wire has somehow become disconnected or corroded at the common spot.

Yep. I had already checked all that. Just simply no power getting to the lights themselves. Switch works, breaker works, just odd.

I just broke down and bought all new Whelen LED’s. Not gonna even mess with them.

Thanks.

About the only advice I can pass on is to use a volt meter or a lighted probe tool (type 12 volt voltage tester into Amazon to get an idea–I’m sure you’re local auto parts store has one) to determine where the open wire or faulty component is. I would probably look first at the nav light switch.
Let me know what you find.
I thought I answered this question yesterday, sorry for the delay.

Suddenly the NAV lights have stopped working. I checked the circuit breaker and it is good, the switch is good, and bulbs are new.

The strobes works, but not the NAV lights. Seems odd. Is there a common ground somewhere?

Any other ideas?

Thanks

Fix: Looks like it was a bad switch afterall. Thanks!
