After a fire.....
could this be the source of fire? the black wire to alternator was pinched between the valve cover gasket and
the head. I could imagine this drawing current from ammeter, and that current also running to starter (which also had a melted solenoid wire). Note that the black wire to alternator is not at all burned going to the alternator, only up to point where the wire was pinched. You cabn see the insulation is pinched, but badly burned only on the side upstream towards firewall/ammeter, not the pinch closer to alternator. Key was not in ignition when the fire started.
