Interior cabin light troubleshooting

Good morning all. I could use some help troubleshooting my cabin light. After checking all the usual suspects, blubs are ok, fuse is ok, and the battery is freshly charged I am at a loss for what else to check. Is it correct that the cabin light is hard wired back to the battery through the inline fuse?

Thanks in advance, Craig

Check ground path

I don't remember how the cabin lights are wired, but you might double-check the ground path. My nav lights weren't working and I found that one of the jumper straps on the grounding terminal block was broken. I measured voltage on each terminal with a DMM - ground, ground, ground, 13V!?

 

Coincidentally I also found one of the cabin light switches was bad.

cabin lights

Toby: Good morning. Thanks I found the problem, there were wires in the cable channel running down the cabin post that were disconnected.
