What I'd really like to do is get the output at various rpms for some of the factory alternators.I had mine rebuilt by Sound Starter and Alternator Rebuild. Been in Tacoma, WA since 1974. Excellent work, easy to work with. A one man shop and it's all he does. soundstarterandalternator.com It's a local business for me so if I can be of any help let me know. I specifically wanted a stock amperage alternator after a misadventure with a pretty alternator that turned out being over 100 amps. He tested all my cores, labelled them by output and rebuilt the one that I chose
Then we'ld have a baseline to judge others on.
FWIW I have a VAT 40 so can check output for an alternator that's on a running engine. If someone needs and is in the area, we can do that.
