It is internally regulated and worked great. Ran an electric fuel pump, Mark 8 fan and an MSD box.

Thanks for the first hand experience. Did it produce enough at idle to run the fans and other electrical items? That is the big reason I was looking at the PowerMaster. Their 100Amp is rated at 70Amps at idle and their 140 is rated at 80Amps at idle. The tech rep said the 140 actually does 85 to 90 at idle, the 80 is the minimum they accept at idle. George was saying the AC/Delco 12SI 94 Amps produce 40 to 50Amps at idle and I was just curious if this is able to run your high electrical demand at idle and keep the battery charged? This car had absolutely no options but when I am done it will have an electronic ignition, electric windows, Vintage Air, electric antenna, rally gauges, and a stereo with a 1200 watt amplifier. I want to make sure there is enough room in the alternator to add additional items in case I need to add electric fans and an electric fuel pump. Do you think the 94Amp alternator would be able to handle all of this at idle and still keep the battery charged?

Thanks for taking the time to respond,
