George,
Good point on the RPM, I was assuming it was engine speed and thought it was not enough amps for that speed. I did not think they could have been talking alternator speed, but that makes more sense. I will see if I can contact PowerMaster and see what they say. If you find out anything, let me know. As of right now I am leaning towards the rebuilt Delco unless these prove to be more efficient at idle.
Some of the PowerMaster cases look like 10SI/10DN and some others look like 12SI. But that doesn't mean anything.
I called M&H Electric Fabricators, they make the stock type replacement harnesses, and they said they use a 12ga wire for the alternator power supply, which according to them is what the stock harness has. So a 10ga, and definitely an 8ga, would be a big improvement.
Thanks again,
Dale
