Thanks for that info Optima Bill! Learned stuff on the horrible 2g alt set up and now some on batteries. It'll be nice info to have around. Well in case any one is interested on what happened with this particular wire I pretty much got it figured out with the help of a few people and some of my past experiences. I ended up taking the harness out and removing all the covering and any tape that the alt wires were on to inspect it completely. All fuseable links were good. I did notice that closer to the the section it jumps to 1 wire (starter solenoid side) the black/orange wire was getting pretty stiff. It was like that for at least several inches. The yellow/white wire was good and the single green this all connects to was obviously toasted. So first thought immediately was that's a prime area for resistance from that point to the solenoid since its closest. I was told its called crystallization but im sure there's a more correct term. Basically it just causes a wire to not conduct properly and makes the end the current is on start on fire or fry fuseable links. So I got lucky and got a complete front harness outta another 5.0 from a wrecking yard. i took this one apart as well and swapped the wires into my harness which was pretty easy. The wires were all good no stiffness. I went and got a Motorcraft starter solenoid (expensive but having the correct length mounting studs was a must) and ordered a 3G alt upgrade. Ill have a fresh battery on the system and should have it finished this afternoon. So hopefully no issues arise and i can finally have the Cobra some what finished!
