Solved: Apparently there are 2 fuses in between the alternator and battery; a 175 amp one and a 20 amp one. Both were blown.

Both are now replaced and truck is good to go.

lol, you said the alternator was putting out. Yea fuses are the first thing you should check. That inline mini , the connector itself has shorting problems. The 175's have fracturing problems at the copper ball, if the least bit bent.

I guess I assumed you checked the fuses. I mean they're right there lol.

regardless, glad you got her goin.

Yeah, this was the first time I have worked on my car. I was kicking myself after I found the broken fuses though. Should have checked that first.

Did you try checking the alternator voltage directly on its terminal instead of the one connected to the battery? Try cleaning your body ground wire using a sand paper or wire brush.

Most Alternator failure is caused by too much wire & terminal resistance or your alternator is too small to supply addional electronic device (amplifier etc.).
