if all seems good then you probably don't have a real problem. But I
would bet there is a wire that may have the insulation burnt off it
....somewhere. Possibly a fusable link that got hot enough to start to
melt (that's what it's made to do" but didn't burn through all the way.
And usually it would be in main output line that attachs fromt he back
of the alternator to the Bat. cable end of the starter solonoid. if
the wire DOES burn though, it will shut the alternator and/or ignition
down, but in general isn't a fire hazard.
