So, I got the beast started after the winter storage. I had to adjust my once it was all purring, I was working on the interior and smelled an odd odour.

Under the hood, passenger side was a plume of smoke, kind of like when some oil dribbles onto the headers. My positive battery cable has a protective fire proof husk around it, and I suspected it came near the I used the handy pry bar to separate the header and wire.

Then I noticed my negative battery cable wire was warm. When I touched the positive wire it was VERY a matter of fact, the plastic insulated coating was soft and easily peeled back with the slightest touch....

Any ideas what has happened? Alternator is new. Is it possible incidental contact with the header caused a heat transfer that traversed the wire to the battery.

So I finally got a day off and some time to climb under the hood.

I pulled the starter, the solenoid was missing a bolt and the second one was half way out. It would appear the torqueing solenoid caused the wires to pinch against the header....melting the wires, and causing problems. I examined the starter + wire from the was melted good, and the secondary + wire to the wiring harness took some heat damage....but it didn't get too far along into the wiring harness! So everything is new and hooked back up...turns over, no mysterious smoke or fires!

When examining the starter, almost every bolt was loose...moral of the story, examine your gear before installing!
