Bench checking the alternator off the barracuda, rotor probably has a short. Brush and holder threads in the casting are practically stripped.

Measured the resistance in the other rotors and determined thats not out of line.
Well the other thing that causes resistance to current is the stator's magnetic field fighting the rotor's.
Nice thing about the squarebacks is that its easy to check the rectifiers without dissembly.

Ground diodes show voltage instead of open in one direction.
I have new spare. Would of course prefer OEM but this will do for now.


Guess I better order that helicoil kit too.
