[QUOTE="Gold miner, post: 6285, member: 262"] Will do! Buggerising around with the motor atm! Found an old 6 volt generator off .... something old?? so I thought feed it with 12 volts, it should turn?? Well it does, but no oomphff! I can stop it with my hand. It has two wires coming out of it, one heavier than the other, in guage, so putting 12 v earth on the body, and pos on the red/heavy wire, the motor turns slowly, but the clamp meter shows nearly 100 amps drawn!!! So, use the smaller wire for pos, and the motor spins at 1600 rpm...but I can stop it by hand..... Then I had a thought, which can get dangerous... :lol: I got the motor going at the 1600 rpm, then ran a pos jumper to the bigger guage wire......hooley dooley...the motor started to go faster, and faster....drawing 25 amps, we stopped it at 3600 rpm.... Any auto electricians out there that might be able to offer some advice? I dont need the speed, just the grunt I also found an old DC motor speed controller, so I can vary the speed, but at the moment, no point in using it coz no power!!! Anyone? [/QUOTE]
