Farm Pro 2425/Jinma electrical help

[Garycw]

I have a 2004 farm Pro 2425 that's not wanting to crank. What's the best way to check soleniod and that it's getting the electrical supply it needs? It had acted up before but not sure if connection problem, key switch or soleniod itself?
Also what it the small push button switch that the clutch pedal pushes in with clutch fully depressed? I had to adjust two stage clutch so pto would engage and adjusted this switch out some. After that I had a shirting problem blowing fuses. This has seemed to have cleared up but not sure what this mini plunger switch is?
Thanks for any help.
Edit: I guess the switch that clutch rod pushes in is a safety switch. Normally open and closed when pushed in. If this switch is bad or not working properly, would this also prevent soleniod from engaging?

The current from the key switch to the solenoid goes through the clutch switch, so if it's not closing the tractor won't start. It's very common to crush the switch if the switch and the clutch pedal aren't adjusted just right.

The switch is an important safety feature. There was a member here who was critically injured a few weeks ago when he started his tractor from the ground after bypassing the switch and his tractor ran him over, crushing his pelvis. So I'm not going to tell you how to bypass it. The switch can be tested with a voltmeter, it is as you said normally open and closed when pressed. The starting circuit runs from the fuse block to the key switch to the clutch switch to the solenoid on the starter. To start there should be 12V between the solenoid and ground, it's the skinny wire on the starter. If there isn't, trace the circuit backwards until you encounter 12V.

Thanks. That makes sense now how it works. I can assure you I'm not bypassing anything. I was also ran over oct 1st when I accidently shorted the starter not realizing it was in gear. Still recouping from hip replacement, but I'm not going to let this tractor beat me. I will fix it. Just being A lot more careful now.

That clutch switch if broken can short out and blow fuses, the clutch rod should push it JUST far enough to turn it ON and the STOP BOLT needs adjusted so that it DOES NOT smash the switch too far in and break it shorting it out.

Thanks Spiker, that switch sounds like the issue that caused ALL my problems. It all makes sense now. After I adjusted clutch in, I had blown fuses, no cranking and the accident that followed. I will check with meter for correct operation and any shorting. I may even be brave enough to do a Tempory bypass to check starting if needed. That will be last resort and diffinetly temporary for testing only.

i'd also add that i would use an ohm meter setting to test the switch with electrics disconencted so no chance of a start and runover, which would be possible testing the switch in a LIVE fashion needing a voltmeter as suggested in post # 2

Thanks sound guy. Good point. I was going to disconnect the POS battery cable too while checking the switch too. It'll also be dbl checked for neutral... Wheels chalked and brakes locked down tight.

 

[Soundguy]

yup.. we don't want no one getting hurt.

This tractor has already ran over me once, resulting in hip replacement & broken toes. I'm still healing, and sure don't want to ever go through that again. I wasn't sure if I could even look at this tractor again, not to mention work on it. But heck, it was my mistake, taking shortcut, tired and not thinking. I picked up working on it right where I left off though.

Wow, a valuable lesson here. My standard practice is to leave the tractor in gear when working on it with the motor off in the belief that leaving it in gear would prevent my being run over if the brakes failed. I hadn't considered the possibility of an electrical fault that could engage the starter, but I recognize that is a real possibility. I'll be buying wheel chocks and keeping the transmission in neutral from now on.
