I need an alternator that puts out good power even at idle, cost is not important, GM, one wire, with a V belt pulley. What are you stereo guys using? Thanks in advance for the leads. Mine took a shit tonight. The Arizona heat, combined with the fact the car doesnt get driven much, and all of the electrical stuff I run ate this one up.
I'd say get the big frame from a school bus. I think they are an S-15. Easy 90 amps maybe up to 140 or so. PM Dirty2 if he soesn't jump in here, he builds starters and alternators for a living.
Late model Cadillacs are running 240 amps or so. Your needing the alternator to be one wire will restrict your choices a lot, I think. Cosmo
Better to add a second battery and diode, one to crank up the motor one to carry any "block loads", If big stereo use a big big capacitor, diode and second battery.
check out this one wire GM style alternator in jeg's catalog...140 amps http://www.jegs.com/cgi-bin/ncommerce3/ProductDisplay?prrfnbr=1651&prmenbr=361 or this chrome one: http://www.jegs.com/cgi-bin/ncommerce3/ProductDisplay?prrfnbr=255175&prmenbr=361
The only reason I said one wire is because that is how the car is wired, I could always wire in a 3-wire if necessary. THanks for the links. I found this one too, the alt at the bottom of the page claims 65 amps at idle http://www.performancedistributors.com/alternator.htm
I bought a plain ol' GM one wire at napa, $50. It's a 65 amp unit. Nothing chrome or fancy, but it's got a warantee
