[Healeys] Headlamp switch

[Michael]

Hi Ross,
The problem could have been as simple as a  loose connection on the switch. 
One of those red wires goes to the sidelights and the other to the panel light switch.
If both were burned only close to the switch heat generated by a bad connection at the switch may have been sufficient to burn the first couple of inches of those 2 wires.
You will need to check to see if there is damage further along either wire to be sure.
New instrument lighting wiring often does not come with replacement harnesses so that would be where I would look next.

On a recent outing I noticed smoke emanating from under the dash when the headlamps were switched on. My 13 year old son thought we were going up in flames and decided to walk home. With the lights off no more smoke or burnt plastic smell occurred and I easily beat my son home. I disconnected the what was left of the two red wires, no damage to any other wires. The switch is the original Lucas unit for a 1958 100-Six. Should I assume that it was the switch that failed or should I be looking for something else. The harness was replaced during the restoration but the switches were kept.
 
Thanks
