After a fire.....

Re. Heritech.org, diagram 3, "the short is in the output circuit of the alternator"
the ignition would have to be on for this to allow current flow/fire? The wiring closest to alternator is not burned, so I'm assuming ign needs to be on.

I never knew that while running, there are times when only alternator current is energizing everything. I always see the ammeter ga. slightly to the right of center.

I've been looking for the ammeter/alt/headlight/fuse intersection but never found it. Maybe now that all the insulation is gone, I'll see it.

THanks so much!!
