I'm having difficulty returning new powermaster alternator purchased through Year One. Seem to be getting the run around. I purchased a 90amp. unit, had the pulley removed and new serpentine one installed at a local starter/ alternator rebuilding shop for $20. Installation of 3 pole same as original that was working fine and same harness.
On startup, blue field wire to resister started smoking. Quickly I disconnected battery. Took new alternator back to rebuild shop to have tested. He found short that fried his wires. Year One about to lose a steady customer having bought thousands of parts for my 2 builds with another Cuda project coming up. I ordered a new alternator from Quality even though only 75 amp, it should handle added electric fans.
