Now that I think back on it, twice in the past I’ve had corrosion on the starter solenoid terminal going to the key switch keeping the tractor from starting, you may want to clean those terminals off as well and / or jump it there with a screwdriver to see if there is a problem there or with the key switch.

I would pull the starter to see if it is hung up in the flywheel and while it’s out I would bench test it to make sure it’s working like it should……you might have a bad starter…( you can take it to Auto Zone and have them test it) If the starter is bad ,when you turn the key to start it will draw down all the current from the battery and nothing else will work like your lights and horn….

Thank you. What terminals would I jump. Depending on whether I’ll try to take a picture of the actual starter maybe you can direct me to which terminals I should try jumping Thank you so much Joe
Sorry I’m late, here’s the pic. But I missed what Larry replied to, mine never lost everything else. :unsure:

make damn sure that your in neutral when jumping , my 2006 foton ft504a just last year I needed to relocate the ground from the batt. somehow there got a resistance between the batt. box hardware where the ground was to the engine. so I relocated the ground to the engine block. Took care of problem with low cranking speed and or nothing happening when attempted starting.

Ok finally have an update on my testing
I tried jumping the two large lugs While the starter was on the tractor and got nothing
I removed the starter from the tractor and grounded the starter to a 12v battery and ran 12V from the battery to one of the lugs and then jumped the lugs with a pair pliers and the motor spun however the Bendix did not object but the motor Spun like a bat out of hell. I did NOT hear or feel any clicks from the solinoid. This test bypassed the solinoid completely. I will not try to wire it up on he bench using the solinoid.

Ok update #2
Bench test of starter.
Grounded starter to meg terminal on battery.
Applied 12v to main lug
Ran small wire from small terminal as shown in the photo to 12v. Result. Bendix ejected but motor did not spin.

Just went through something similar with my Jinma 284. Turned out that the main contacts inside the solenoid were burned/worn just enough to cause high resistance. This in turn kept the motor from turning.
Solution was to remove and dismantle the solenoid. Some soldering required. Once inside I cleaned the contacts on a wire wheel and re-installed. Lubed all the proper places while the starter was apart just for good measure. After 600 hours in 11 years I chalked it up as routine maintenance.
As always on any vehicle, make sure all wiring connections are clean and tight. Especially the ground circuits.

Thank to all for the help. I finally got back to my farm where the temp is over 32 degrees today so I reinstalled the starter hooked everything up and nothing. Cleaned all the contacts have over 12v at the battery. So I disconnect the battery cable from the starter and run some jumper cables between the positive of the battery and the battery lug on the solenoid and what do you know lights come on and I’m able to crank. Install a new $10 2 gauge battery cable on the tractor and it fired right up.
See my new post about two other electrical gauge issues 🙁
Thanks again for your time.
Joe
