Kingy, wiring the starting circuit is pretty straight forward. Battery negative to the frame, battery positive (heavy wire) to one side of the solonoid, other side of solonoid (heavy wire) to the starter motor. Then it is usually the case with the 2 small terminals on the solonoid, one goes to earth (frame) the other goes to the ignition switch. From the other side of the ignition switch you run a wire back to the battery live side of the solonoid.This puts power up to the ignition switch, you turn the key, this powers the solonoid and the motor will crank over. Then you will need to tell us if there is any wires coming from the upper part of the motor and this will be the charging circuit. Good chance the might have been chopped off
