Case 220 Electrical issue

David Shirk · May 19, 2013

I own an old Case 220 for short work around the home. It just keeps running...but right now it won"t start. I need some advise on what to replace. I am a carpenter, so this electrical is out of my realm of expertise. A varmint chewed the wiring under the hood and exposed the copper core...thus causing a short unknowingly. While running, it made a pop...but ran until shutting it down. After surveying the bared wires (and replacing them one by one), it just will not turn the starter. I tried jumping the solenoid (ignition on), and that does turn the starter...but it will not fire up. Is the voltage regulator burned up? The solenoid? I hate to just replace everything to get it running. Any help would be appreciated. Thanks

Have you tried jumping directly to the starter? Do some research on the safest way to do this and then give it a try. You will at least know if there is a problem with the starter, which will then give you a place from which to start your trace backwards to find the component that is causing the problem.

Thanks for the advise. I have jumped directly to the starter, and it does turn over. It just won't start (just spinning the motor over)...and generally it starts pretty good. I checked the fuse link from the ignition, and it looks good. I'm just not versed in auto/tractor wiring. It's as if there is a connection missing to complete the cycle.
I can wire a house, but this is a bit different.

here is a wiring diagram one for gen/starter style other is for later style, I would start by seeing if you have any power at the ign switch then go from there you should have two safty switches also one on the pto one on the fwd/rev control

Thanks for that information. It should help a lot.

Fusible link can look good, but be bad. Check with a multimeter.

Your starter is just a motor like your circular saw only DC current. If you have used jumper cables and bypassed the solenoid running power to the starter, check if there is a ground problem. Also run a wire directly from the body of the starter to the negative terminal of the battery. If it still doesn't turn over you need to send the starter off to be repaired.

The starter on my 210b did that. I took the starter off and wired it to a battery on the bench and it worked and put it back on the tractor and it didn't. I solved the problem by cleaning all the rust, grease and dirt that was between the starter and the block.

Thanks for your input. I do get the starter to run "in place" by jumping the two terminals on the solenoid. But the engine won't fire up. Trying to reason it out, if the solenoid is bad, it still should start by jumping when the ignition is turned on...shouldn't it? Perhaps it is a ground. I'll keep searching.

David, that is why I would start at the ign switch and see if it has power to it and thru it, yes with the key on and by jumping across the solinoid it should ave started, my guess is that you do not have power to the points and since you lost starter enguagement at the same time that is why I feel you have no power to the ign switch and if by chance you do have power to it it is not going thru it
