Hi, Bruce -
Yes, I used a Starter/Generator for a golf cart. Worked well, for a while -- when I was only charging it's battery - but when I added the cooling fan to the radiator (with a thermostat/relay) the draw went up by 7 amps and I didn't have the voltage regulator adjusted to account for the added draw - soooo, dead battery! I disconnected the system for the time being ('til the power comes back on - hand cranking) - then I'll play around with adjusting the voltage regulator to get the correct charge rate - at my leisure! It's hot as hell and the generator is still going strong. Day 6 - 110 hours!
