All mopar of this era to my knowledge dash lights come on via the headlight switch . Usually an orange small gauge wire .
The headlight has to be in park lights or head lights , then it goes through the dash dimmer resistor to the dash lights . If a short in dash lights it can burn out that dimmer resistor wound coil at the front of headlight switch , but usually will still go on at one ( bright ) end . Often these dimmers are corroded and intermittent — can be often fixed by vigorous turning back and forth if not burned out .
I think on some there is a dash light circuit breaker inside headlight switch sometimes a fuse . Look up any dash light , on print , follow wire # to source . Will be headlight switch .
. Happened to be working on F,G H harnesses last week ( a moron cut them all — right at firewall ) and noticed G or H has an added small fuse taped to harness up behind speedo for the luminescent power supply only , which connects eventually to that same orange 12v dash light wire . Failure of that supply ( it shorts?) must blow light dimmer .
Internal fuse or breaker seems not to protect the dimmer from shorts. It melts first . Unless dash lights full on .
So, this must have taken out headlight switch dimmers in 60? Obvious a running factory change and not on print I had .
What shorted to burn your Harness ?
On one of these the heavy green wire in the kick panel with a fuse in it (60-61) used to power seats (?) (or something ) shorted out by cutting into insulation like a razor knife on the very sharp edge of the metal access opening in kick panel , where three breakers are , —— before the fuse of course , taking out whole harness behind dash out to battery . Junk now . Wires destroyed by main ones melting .
Heads up on dressing that green wire carefully . I put added sleeving on some of those wires , there .
Ps also noticed on all three harnesses , severe corrosion on feed to dome lights ( pink) at bottom of kick panel in body wiring connector there , and also corrosion on female end of heavy PS feed wire at seat . These are alive at 12 v at all times , dampness in rug or jute must cause this .
So no lights on roof .. or no P seats
