| Okay those would be the Gm-Delco Delcotron and they run from 43 amp to 68 amp output ratings at 14 volts, some were as high as 75 amps for single drive belt. Yes you maybe spinning four of them over. BUT you will not be able to pull full ratings out of all of them at the same time. If I was to put an amp-meter on each output lead it's very likely you are only putting out less then 25 amp per unit. Lets do the math. 4 Hp X 500 watts= 2000 watts 2000 watts of power is all that you can get out of that gas motor. That also doesn't account for the power losses of your drive belt. I don't care if you are spinning one or ten alternators the total power you can pull is 2000 watts. That works out to 143 amps at 14 volts. Yeah I can say I'm running a 10,000 watt genset with your 4 HP motor and in fact I can but you slap that system with a 4,000 watt load you A. slip the belt or B. kill the motor. Being able to spin over the alternators is one thing pulling their rated power out of then in something else. My big worm drive skillsaw will kill my friends 2000 watt genset if I try to cut to fast with it and the saw is rated at 1750 watts... --- On Sun, 10/16/11, Lochadio Who <lochadio@yahoo.com> wrote:
