I am electrical specialist and I will try to help. The starter solenoid is probably being pulled electrically. You need to make sure the battery cable is on one of the large terminals on the starter solenoid, and the cable to the starter is on the other large terminal of the starter solenoid. If there are any small wires that have the large ring terminals on them where the go on the large terminals of the starter solenoid, they MUST go on the large terminal that the battery cable attaches to, and NOT the large terminal that the cable to the starter wire attaches to. Set it up like that and temporarily remove any the small wires from both small terminals, and see if it still cranks when the battery is hooked up. If that stops the problem go through all of the small wires on the two small terminals. Then find the one wire that is hot with the ignition in the crank/start position. That wire goes on the small S terminal of the solenoid. Any other small wires that go on a small terminal go on the small I terminal right beside the S terminal. Go over all of that and let me know if you have any questions, if you do I am here to help. Good luck with it, have a great day and thanks for using Just Answer.
