Travis, > I will use a DC/AC power inverter for the power supply. It's gotta be a > hefty one, 500-700W. Can anyone foresee a problem using this? Doing a little math tells me that 600W is going to draw close to 50 amps from the alternator. You are going to have a hard time getting this kind of juice from a normal alternator at a reasonable duty cycle or any alternator at idle speed. While I was at a local alternator rebuild shop to get my truck alternator fixed, I brought two John Hervey alternators to see what they would do on his test bench. I don't mean to sound like a commercial, but the 150 amp version of what he sells may be your ticket. I asked about other alternatives, and the shop owner told me that the 150 I brought was about the best anyone could do with a conventional design at low RPMs. There are beefier designs, but they don't put out well at low RPM (idle). If you go this route, then you might need to come up with a way to make your car idle at 1200+ RPM. He told me about another option which was using a "generator" as is used in large diesel trucks. They put out gobs of current at low RPM, but they are big & cost a bundle. It would barely fit in the stock alternator location in the D (if at all) and it would cost around $800 - $900. If I understood him correctly, they start out with something on par with household AC and then turn it into DC to run the truck. If this is correct, maybe you could use such a setup to run your BTTF accessories and skip using the inverter. I would love to find a way to make my car run continuously at idle without eventually killing the battery. No alternator can do this -- not even John Hervey's. Walt ------------------------ Yahoo!
