3415H Wiring

[BradW]

Hello, I am in need of a wiring diagram for a 3415H, the solenoid works, but the only way to get it to crank over is to "hotwire" it from the battery to the post on the starter, thanks for the help,-BradW

Sounds to me like you have a bad or non engaging safety switch. There is one under the seat deck to keep it from running if tractor is not in neutral. There is another on the inside of the frame near the PTO lever to keep it from turning over if the PTO is on. If you have a front PTO there is another in the same place on the other side of the frame, if not there should be a loop of wire with spade ends stuck in the wiring clip. You can test to see if it is one of the switches by pulling the clips one at a time and putting similar loop of wire in each clip as you tes by tryng to crank the engine. Do one at a time and replace each clip as it was until you find the one that is bad. If that yields nothing, put an ohm meter on it with one wire on each side of the solenoid and test for continuity when you turn the key to start. If solenoid is working, then put a loop of wire in all the safety clips (in case more than one is bad) and try it. If that yields no results you probably have a broken wire, or the keyswitch is bad. You can test all that with an ohm meter too. Sam

Brad, I had the same problem with a 7016. As Sam said, check the safety switch connections. Mine had a front PTO and there were three of them. As a tractor gets older the connections get a little rusty/dirty and dont make good contact. you have to get underneath the tractor, pull the connectors out and clean them.
