Ok I did a voltage drop test as suggested. Here are my findings
engine running battery voltage = 12.57volts
positive charging stud to positive post = 5.5volts (I wasn't sure on which one the positive stud is, I thought it was the big black wire on the alternator) (not the ground wire)
green wire on alt to positive post = 10 volts
blue wire on alt to positive post = 9 volts
alternator case to negative post = .11 volts
voltage regulator mounting bolt to negative post = .10
I hope this sounds right not sure which wire, blue or green on the alt to check with positive post. I tried to find the info up top but was unable.
It looks like to me that the ground side is ok but the positive side is messed up. Should I run new wires from alt to reg. I think the service manual shows that there is a tie in to one of those wires or both inside the wire harness. thanks again for all the help
Common sense will say if both leads are on a positive, how can you have a reading?
In a "perfect" world you would have a reading of 0. In real world a reading of 0 indicates other problems, but any reading over a few decimals such as .3 is also a problem.
I find it odd that you coincidentally have 2 different bad wires, but not surprising. OR there is a problem somewhere where they are spliced together?
I know everything meets at the battery post but do not know if they meet somewhere further down the line.
