JD 2010 12V starter issues

[JMDREW]

I purchased a '62 2010 Diesel last summer at an auction from a family friend's estate. Struggled with starting over the winter for plowing. The other day, I went to start it and it churned for a little bit and then completely stopped. No click, no hum, no nothing.

There are two starter solenoids in line, a smaller solenoid connected to the solenoid on top of the starter. The wire linking the smaller to the original melted down and there is a lot of scorching on the face of the original starter.

I pulled the + cable off the battery and replaced the wire, hooked everything back up and when I pressed the starter button got one click and then nothing. If I disconnect the battery and reconnect it, I'll get a single click and then nothing. I'm assuming that one of the solenoids is fried? Any suggestions or ideas?

I have looked at the wiring diagrams for 12V and this tractor only has a single battery. There is also a LOT of spliced, jumpered, and old-farmer- engineered wiring behind the dash. I'm going to have to find a wiring diagram to clean that mess up as well.

What they have done is take a second solenoid to power the starter solenoid. Many of these older tractors have a voltage drop in the factory start circuit by the time it get through the key switch and any safety switches. So they take battery power into this second solenoid so the factory circuit just energizes the small solenoid not the main starter solenoid. The end result is the starter solenoid has higher voltage to engage better when the system is loaded cranking.

Take a volt/ohm meter and check the voltage your getting every where before and after trying to crank the tractor. It sounds like you have a bad switch or solenoid. It is not allowing voltage/amps to make the starter solenoid work correctly.

Thank You! Finally got back to the tractor and it is the "big" solenoid on top of the starter that has failed. As I'm searching online, I'm not seeing 12V versions of that solenoid (Cup on the back with the little button inside). Can I run a 24V solenoid with the current setup? Would the previous owner have left the 24V starter and solenoid in place when converting to 12V?

Is your starter a Delco starter??? If it is just go to an auto parts store and buy a solenoid. Also your JD 2010 Diesel would have always been 12 volt. They did not use the 24 volt system like the Waterloo tractors.

This is the most common Delco solenoid. The picture is the one I think you need. Delco # 1114251 They cost $25-$30 ]

No, the solenoid has a cylinder at the end that slides into a housing on the starter.

Can you please post a photo of your tractors starter or the number on it's ID tag?

I'm at work but the starter looks exactly like this one:

 

[JMDREW]

Oops, wrong image, that's the one I was looking at: The starter I have is like this:

The solenoid is bolted to the starter housing. There is also a smaller, box solenoid wired in series between the starter switch and the starter solenoid.

Your tractor evidently doesn't have a factory type starter.

Well, I'm going to need more information: Ordered a "4010 Starter" like the one you showed. Here it is next to the starter that was in the tractor:

The bolts line up, but the bendix gear is too small and it is significantly undersized.

I'm also pretty sure that this tractor was originally 24V with two batteries as there is a diagram sketched on the battery box showing wiring for TWO batteries and the light switch on the panel has connections for BATT A and BATT B.

New starter in your photo is designed to bolt on RH side of engine not LH side of engine as old starter. Can you please post a photo of your 2010 tractor?

Jim, the way I remembered, the starter solenoid is near the bottom of the OEM starter, and here's a photo that seems to confirm that...

Well, Now I just feel stupid. One typo at the beginning of the thread and I had you guys trying to help me with the wrong tractor...

My tractor is a[b:e5140b1122] 4010[/b:e5140b1122], 1963.

I apologize for leading you down the wrong path. Explains the confusion, though...

If your tractor has been converted to 12 Volts I have some conversion information and diagrams that may be of help.

Email me,if you'd like a copy forwarded to you.

How many teeth on the starter drive on the replacement starter... The diesel starters used 10 tooth drives, the gasser starters used 9 tooth drives. Maybe you got a starter for a gasser?

Thanks for correcting my OOPS.
