I am building an electric tractor and got all my motor controls and switches in today, So I had a few min I figured I would hook it up to see how it all worked together. Two 12v deep cell battery's to a 3 position 6 pole toggle switch to reverse the polarity, then to a dc motor controller to the motor. sounds simple enough?? I had this all hooked up before but the other motor controller was not big enough and burned out. Now I have a big enough motor control and figure I am good to go. tuned the switch on and instant fire!!!!!!!! burned every ground cable rite of, I thought I was going to burn the garage down for a few minutes!!! Had to rip the positive wire of the battery's to get it settled down.
Turned out the motor controller is shorted out, puts voltage straight thru it no matter what you do, So not I have burned up all my new switches and wires and am still no closer to having this thing going. In the end some of this is my fault, I did not put a fusible link in there, I was going to go get one tomorrow so I could use it when I did the final install, I should have put one in tonite but I wanted to test it out and see what the speeds would be like. Oh well now that I have vented I feel better. Pic is of the motor install the other day, I did not get pics of the burned mess tonite.
