Tail lights are probably the same fuse as the dash lights on a 66. Radio
should be seperate fuse, brake lights another seperate fuse, and interior
lights usually on its own fuse as well.
Sounds to me like someone did some creative splicing of all those circuits.
If you are not comfortable with electrical work you are going to hate this
job but I would start by looking for some non original wiring that has been
spliced and added to the factory harness. It sounds like everything you
mentioned is all drawing off the one fuse rather than a short. Good luck.
"Opportunities are spawned from crisis"
My Elky started blowing fuses, seemingly out of the blue. I have
tried to figure out exactly what happens prior to it blowing, but
haven't been able to isolate it.
The fuse handles:
-Rear running lights
-Brake lights (but not rear turn signal lights)
I turned on the radio and left the door open without the engine
running for some time, nothing happens. I do the same with the engine
started and the lights on, same.
Any idea how to troubleshoot this? I'd hate to take the dash apart
trying to find a short. I drove it for two days without a problem and
thought I was home free, just to be let down.
The wiring harness is original.
Thanks in advance for any help.
