So my 91' 7.3 idi has been doing some weird stuff lately. Ive always had little electrical quirks. As of late my batteries are dying over night. Theyll charge fine once i get the truck running but if it sits a few hours its a hard start if it starts at all. I've also had to replace my windshield wiper switch once and my headlight switch twice. Well after replacing my light switch this last time, my voltage started going through the roof. Driving to work my ac compressor started making a God awful noise, pulled over popped the hood and the red power wire was melted and the compressor smoking. I grabbed some channel locks pulled the wire and the pulled the belt because the compressor was seized. I jumped back in and noticed that voltage was maxed when I went to take off. When I accelerated it spiked, at an idle it seemed fine. Limped it home home in 5th gear at 600rpms because if I went faster the voltage spiked. Any thoughts on what it could be? Voltage regulator? I think I have one that's kind of by my starter relay but have read there's one also in the cab? Any advice would be appreciated. Electrical stuff is not my strong point and feeling a little lost.
