    You will have to back trace the wires from the switch, (1) One wire from switch should go to + side of the battery. (2) Another wire from switch should go to the starter selenoid, will have power only in the start position. (3) Another wire from switch should go to the ignition on the motor, this wire will have power to it when the switch is in the start and run position. Or bypass switch, go to the motor and find the wire going into the ignition, this will need 12 volts to it at all times. Then you will have to find the heavy wire going to the starter. Use jumper cables, attach the ground from the bat to the frame of the unit. Then flash the wire going to the starter, when motor starts remove battery pos from starter wire. The unit should have a selenoid on it.

    BE CAREFULL!!!! not all engines need 12 volts to the ignition to run. Most engines just use this wire to kill the engine and if you run 12 volts down it, IT WILL FRY THE IGNITION INSTANTLY!!! Tell us more engine info, and i am shore some one can help.. But usually pull the wire coming from the ignition, which ungrounds it, go to the solinoid there shoud be a small terminal on the side apply power here and the solinoid should click.. then the engine should turn over.. no click solinoid is proably bad. yes click but starter don't turn, bad connection or bad starter.. this ought to get you started...

    Later snapper...
