starter motor will not stop running

homebre973 · Aug 24, 2014

I put a new ignition switch into my IH 340 tractor in the Spring, and it worked find. Now 3 months later, when I went to start the tractor by reattaching the battery, the starter motor keeps running and will not shut off unless I disconnect the battery. I can turn the key in any position and nothing happens to stop the starter motor. When I disconnect the battery,then everything stops (generator is shot). Any suggestions what is going on? Thanks

either solenoid or starter switch.

if you have a multimeter, disconnect battery cables from solenoid, check battery cable to battery cable; should not have continuity, if solenoid is good. if you have continuity, replace solenoid.

could be a starter problem, however very unlikely.

Try disconnecting the small wire on the starter solenoid first,hook up battery and see if it still tries to crank.On the 340,the small wire comes from the starter button,which gets power from the key switch when you turn it on.(Unless yours is wired non factory!)Mark

Thanks, since this is a 1965 Tractor, I am not sure it has a solenoid. I disconnected the ignition switch and the starter motor still ran. I am thinking there must be a short in the starter wire. I will check the continuity from battery cable to battery cable. Thanks again.

Trace the path the battery cable goes from the non-ground side and that should lead you to a solenoid. Common for them to stick when they are getting wore out. By the way if it is a key start it has to have a solenoid the ignition switch is not heavy enough to handle as many amps as a starter draws.

if you have an ignition key to turn to start, then you definitely have a solenoid.

Sorry if I am not knowledgeable about the hook up of the electrical system of the tractor, but there was no starter button that was in use. The person who sold it to me maybe bypassed it and is just using an ignition switch. Thanks.

That is why I said to trace where the ignition side battery cable goes it will go to a solenoid. Or trace back from the starter it should have a big cable on it and that in turn goes to the solenoid

If you had a short the wire would burn up. Your sww must be stuck in the start mode as thats the position it needs to be for the soleniod to energize then when you release the sw it springs back to run and then the starter would stop as only time starter should turn over is when you hold the key to the start position. Sounds like you better get someone who knows how to wire and trouble shoot your system.

i had something similar happen to my ih 3588 it was
caused by trying to start the tractor with a weak
battery i believe
they called it low voltage engage or something like
that where the starter solenoid engages but wont
release due to low voltage passing through

Not an uncommon problem. Take the starter and solenoid off and take it to a reputable repair shop and make it clear to them what it is doing and have them correct it. The problem IS the solenoid! But the solenoid could be reacting to something else bad like the starter drive. Get it corrected it can be hazardous.

Thanks to everyone. I did find the solenoid--it was mounted away from the starter motor. I saw a picture of one on the net, so that enabled me to locate it. I hit it with a piece of metal (lightly!), and then connected the battery with the ignition switch not connected, and the starter did not run (good!). So this seems to be the problem. I have not had time to hook up the ignition again, but will try this weekend.

I put the ignition back in and started it. The starter kept running again, so I tapped the solenoid and it shut off. I assume that means it is the solenoid. If I can get the old one off, I assume I can just order a 12 volt solenoid that would fit the IH 340 utility. Thanks.

old · Aug 26, 2014

Order one heck it is a common part used on many machines. Take it off and go to a auto parts tore and they should be able to hand you a new one

homebre973 · Aug 29, 2014

Thanks again. I got the solenoid off but it is a 6v solenoid. The battery is 12 v. Should I replace it with the exact same solenoid: DR1465 6v? I assume so since it has worked for at least 10 years.

6 volt solenoids and starter will work just fine on 12 volts but a 12 volt solenoid or starter will not work on 6 volts. As long as the 12 volt one is wired the same as in the same number of posts you can go with either one your call

Back again. I replaced the solenoid, started right up, but wouldn't stop again until I took the battery off. I am recharging the battery now as someone mentioned, but I have the ignition switch out. I have a multitester. The ignition switch has 3 bolts around the periphery and a center bold.
1. In the off position (farthest counter clockwise): battery and ACC show continuity, but no other combinations.
2. Next position clockwise, nothing shows continuity.
3. Next position all three outer posts show continuity with each other, none show continuity with center post
4. Last position, center post shows continuity with ignition post.
This seems correct to me.
Any suggestions would help. Could it have been a weak battery? If so why? Appreciate the help.

Sounds like a universal type ignition switch to me. It should have a Ig an ACC a BT and a ST terminal on it. The ST is the one for the start position and should only be hot when held that way. Try this. Take the start wire off the solenoid turn on the ignition and be 1000% sure it is out of gear and even better blocked so it can not roll then touch the wire you took off back on to the solenoid. If it spins over when you do that likely to have bad switch of a wire that is shorted together with a hot one

homebre973 · Aug 31, 2014

Well, I am just about to give up. Used a volt ohm meter and found there were a connection between the ST and the IGN wires without the key being in (low OHM reading). Stuck my hand under the "dashboard" and tried to jiggle some wires to see if any were touching. Put the ignition back in with all the wires attached, but when I turn the key now after seeming to start up normally, it started making a different sound as the starter spun. There was no indication that the motor was actually turning over. The starter armature was moving but the sound was wrong. I am wondering if the contacts on the starter are worn away. However, I have no explanation for the sound change, though the starter is not staying on now unless I have the key in the ignition position.

Put that meter away and use the simple troubleshooting way I tell you. Take the small wire off the solenoid. The turn the ignition on making sure it is out of gear. Touch that wire back on the solenoid and if the starter turns the ignition switch is bad or you have a short and just reaching in and feeling will not find a short you have to look with your eyes and see every thing which I know is not easy to do. Meters can and do give false reading at times when it comes to volts

homebre973 · Aug 31, 2014

I didn't mention that I did that after I wiggled some of the wires. When I took the wire off the solenoid and turned the ignition switch, it did not start. When I put it back on the solenoid, the starter motor spun but nothing happened. The sound had changed also. It seemed like the starter was turning, but nothing was turning in the engine. I put the tractor in gear and turned the ignition, the starter turned but nothing else happened.

Sounds like the starter drive is bad or the flywheel has burrs on it stopping the drive from engaging the ring gear

homebre973 · Aug 31, 2014

Thanks for your help. It's always something. The guy who sold me the tractor should be back this week, and he is a good mechanic, so maybe he can tell me what it needs. It may be a new starter motor.
