69 B body Tail light Dash lights Inop
 

Here is the lastest problem I currently have no tail lights, instrument lights, marker lights or cigarette lighter. I have read through some of the posts regarding this issue. I do have power to both sides of the 20A tail light/cig lighter fuse. My brake lights, headlghts, flashers and signals all work. Any suggestions????

Pull the fuse block and trace the power feed wire... I beet you will find that it lost its power from the source.... That wire might run threw the firewall. Check it good..

Keep us posted...

If I have power to both ends of the fuse. How can the circuit not be powered?

Also, the instrument lamp fuse is not being powered.

Sorry... My bad... I read it wrong....

Sounds like it might be a issue with the headlight switch or the dash panel switch.
I think it goes from the fuse to the dash panel switch first. Check to see if you have power up to that point?
