Excess current in Ignition 1 circuit?

Excess current in Ignition 1 circuit?

Don't go away mad, Redfish. I was not discounting your reply by acknowledging Lonewolfs - despite how it might have sounded. That was not my intention.

The most likely suspect, however, is the switch connector itself.

This is what I would like to think since the problem surfaced after installing the new switch.

You have any added loads, upgraded ignition, etc?

Electric fan with relay but it's tapped at the starter relay. Have not changed the ignition (been running FBO for years).

And I assume you don't routinely leave the switch "in run" with the engine off?

I do not do this.

Is there any evidence along the "run" circuit of damaged insulation or other heating?

Not unless there's some recent damage I'm unaware of. Car is mostly for show with very little use. I'll have to do an inspection to rule it out but it's doubtful.
