Larry , you are 100% right , loose high current connections make heat. There has been mention of burnt connections in the forum but doubt it is the primary cause of fire. I would guess the rebuildable after market glass fuel filters to be high on the list of fires. I removed the one on mine that the previous care taker installed. Sorry if I sound like Chicken Little , I am a elctrician and specilised in fire systems at a hospital.
The Pantera has a number of poor electrical design issues. ( like overloaded ignition switch and main fuse panel) The amp meter would have been better served with a shunt type meter as in GM vehicles.
Upgrading to a high output alternator needs upgraded wiring , I doubt any one would run #2 or 4 from the alt to the meter then on to the battery. I feel the expanded scale volt meter gives more useful information.
I do acknowledge keeping things looking original may be #1 with some owners , I like to make minor improvements that the factor should have done while keeping it reversable. After all we are just the current care taker.
