Assuming you still have a starter problem, lemme try... Tractor in neutral!!! Have you taken the starter COMPLETELY OFF the tractor, put it in a vise (hold it tightly - lots of torque) and "jumped" it? (Ground attached anywhere on the starter body, hot wire attached to the insullated lug on top.) What happened? If the starter just sat there, it's bad. Take it to a shop for a rebuild. If it spun up, it's likely OK, so we need to find another problem. Put it back on the tractor. You've already cleaned the paint off for a good contact. Now hook up the ground jumper cable - no paint!! - and touch the hot jumper cable to the insullated post, just like in the vise. It should work if it did in the vise. If it doesn't the starter is in a bind. Is anything "forced?" Over tightened mounting bolts? Paint making an uneven mounting surface? Next most likely spot is the battery posts and cable terminals. Clean and tight, you say? New cables? OK. Connect the battery back up. Next is the starter switch and solenoid wire. The switch sends juice to the solenoid, which then closes and connects the battery current directly to the starter (just like in the vise.) You need to see if the ignition voltage is getting to the solenoid. Take the small wire off the solenoid, turn the key to start and touch the wire to a ground. Sparks? Its OK. Nothing? Problem is either in the switch or wire. Now using jumper cables, ground to the tractor someplace and touch the hot jumper cable to the small post on the solenoid where you removed the small wire. If the starter spins, the solenoid is OK and the wire or switch is the problem. If nothing, check that the solenoid body is grounded to the starter body - sometimes with another wire, sometimes through the metal mounting feet. Clean off new paint under the solenoid!! Try again. If OK, problem is definately in the wire or switch. Hook everything back up, and touch the hot jumper cable to the starter post on the ignition switch - usually the center post, sticking out a bit. If the starter works, the problem is the switch. If not, you've got either a bad wire from the battery to the switch, or from the switch to the solenoid. Is there a starting resistor in the circuit? That can interrupt the starting circuit. Just "connect the ends" and jump through the resister. It'll be OK for a while. If that works, problem is a burned resistor. Easy to replace. So, how'd we do?
