Starter troubles YM2000

[buckstoy]

Help! 2 weeks ago the starter on my tractor started acting up. When I tried starting it the lead off of the solonoid would smoke. I took it to my local starter repair place and they rebuilt it and put a new solonoid on it. I reinstalled the starter and it worked fine for about 5 starts and when I turned off the tractor I heard a "whirring" sound, the engine was off but the starter was spinning like crazy! I pulled the negative lead off of the battery and it quit. I attempted to remove the lead from the ignition switch and reattach the negative lead but the terminal would arch. Took the starter back to the rebuilder and they replaced the solonoid with a different style solonoid. I've re-reinstalled the starter and again gotten about 5 starts and again the whirring sound of the starter spinning like crazy. Is it something on my tractor causing this or just crappy solonoids?

The solenoid is sticking,, keeping the starter engaged or the start switch is sticking in the start position which would keep the solenoid engaged

Next time.. take the wire from the switch to the solenoid off,and see if it stops spinning

Ignition switch would be a good reason. What it sounds like to me. Sticking and Staying in the Start position. I would Disconnect the Battery and on the Key itself spray some W/D40 on it and put the key in the switch. Turn the key and try to loosen up the Ign. switch. Don't put an excessive amount on it but just enough to try and free up the switch. Do it a few times and see if that takes care of the problem.

Replace the ignition switch, probably shorted and original problem.

I removed the wire from the switch to the solonoid and attempted to reconnect the negative lead and it shot sparks.

The first failure was just an old wore out starter with to much friction inside causing too much current draw and smoking the lead on the solonoid. These last two times after rebuild , I've started the tractor a handful of times, turn off the tractor and the starter is spinning away without engaging the flywheel.

Two different solenoids bad ? That so highly doubtful. And a repair shop rebuilt it ? They tested the starter after rebuilding it I'm sure The first one may have gone bad but if it happened twice then something took them out. I have a Ym2000 that I was all through the starter BTDT. I was even in the motor and reversed the brushes and was able to get 3yrs. more use out of it before having to rebuild it. The shop that rebuilt it commented on it knowing what I did. They were Gone :laughing: Take it back and if the solenoids bad again there's not much doubt somethings causing it. Most likely Ignition switch Stuck and burning it up. I had this rebuilt 5yrs ago and it's still working. And for just about the cost of the solenoid posted. So it's an EL-Cheapo!

sounds like a bad ign. switch to me. You can test with a test light ,or by touching it to the solenoid switch terminal
