Woah now.

The only black wires om my headlight switch are from the front corner of
the plug and are the switch 'grounds'. They are not power lines.

The red wire with the white stripe on my switch is for the headlights.
It goes to the dimmer switch.

Re: Fire Damage Wiring Repair
 

I'm getting lost in your symptoms here.

You had an electrical fire of unknown cause at your GM-style light
switch and replaced the switch and pigtailed harness. You are certain
that you wired the switch the same way that it was.

Now your highbeams or low beams blows a fuse. Which fuse? What legend
appears next to it at the fuseblock? What (else) goes out when that
fuse pops? (Fuses pop for one of three reasons: Accessory overload,
short to ground before the load or local overheating.)

Your dash lights come on with the keyswitch in the ON position with the
light switch OFF? This would be general instrument illumination lights?
The ones that can be dimmed down with the reostat? Can they be dimmed
at all? Do they work with the key off?

The reostat on the light switch now becomes smoking hot. In all
positions or only with the dome light is switched on? Does it matter if
the door is open?

A left-field question: Has the radio recently been replaced? Lighting
and keyswitch-controlled accessories are generally well seperated
electrically, but the radio is often one place with both feeds plus a B+
feed.

Mike:

Yes, it is the high beams that blows the fuse. I am going to replace
the dimmer switch today and see if that cures that problem.

Re: Fire Damage Wiring Repair
 

Please tell us 'what' fuse blows. Even it's location in the panel, then
I can look in my book and maybe see what circuit is bad.

The headlights are 'not' fused so something else is shorted with the
highbeam wiring.
