Starting issues with john deere 2040

[kshunter]

Hey guys, ive tried to get help and all the things im doing just arent getting this tractor to turn over. A little history- its been sitting outside and hasnt been started in a year. I have the keys and stuff, but all of the wires from the back of the ignition are unplugged (no idea how that happened). The guy who used to operate it for us a few years ago always hotwired it to get it started up, even before all the wires became unplugged. By hotwiring it, i put a screwdriver on 2 different pieces of the starter, and all it does is spark? I know the starter is good though because ive taken it to the shop and it was working fine. I have no idea what else to do? thanks

Among the many problems, maybe the battery just doesn't have any ooomph left. Or the engine is siezed up for one reason or another.

But sounds like it is time to do some work and get the wires reconnected and things hooked up correctly. Starting with a screwdriver has its issues.

Haha yes i definately understand, ive gotten pics of how people had theirs wired, and it just looked WAY different from mine and the manual doesnt say much. It was started last year so im 99 percent sure its not seized. And both the batteries have been replaced

Take a look at jdparts for some info on what parts are involved.
Here is a sample of the 2040 wiring diagram shown that may help get things plugged back in. Maybe get a new ignition switch as it may have been the first thing to go (that or the key was lost )

I still wouldnt know how the wires go back on correctly

Evidently you didn't pay very close attention to dntfxr's post on another thread of yours on the same issue. The photo he showed only had three(3) wires on the ign switch(AR58126). The hot wire with electricity from battery attaches to terminal "B", the wire that excites solenoid attaches to terminal"S", and remaining wire attaches to terminal "I". Not that difficult.

 

[kshunter]

Yes ive gotten those wires plugged in correctly, and nothing happened? But there was about 8 more wires that I still dont know where they go and havent found any diagrams for them. The were wires for like the spedo, tacho, and probably a few other things. Where are you getting those diagrams from so i can take a look at them myself?

 

[dntfxr]

Ks, the diagram I posted was from the JD service manual. You can buy one on eBay, great to have just in case. The one up top is from JD parts website.
I'm going to guess that the other wires may have come from the light swtch right above the ignition?
I know you probably have this covered but make sure both shifters are in neutral or else it won't turn over.

 

[kshunter]

What page #/ section from the owners manual, because I have it. And yes I knew that, but thanks

 

[dntfxr]

It's the tech manual, the service manual that the mechanics use at the JD dealership. Not the owners manual.

 

[kshunter]

Im sorry I said that wrong, I meant the tech manual

 

[dntfxr]

No problem, it's in section 40, pages 10-4, 10-5, 10-6, and 10-7. Do you have a test meter? You may need to test each wire and possibly run new ones. Have you tried to pull start it to make sure the motor is free?

 

[kshunter]

Not yet, me & my dad are gona use his dually here when he gets a chance. Last time we went we were going to, but the chains I thought were in the barn werent there.

kshunter
What is your previous experience with engine mechanics, or tractor mechanics?
Just curious here, and it may help guide you along.

 

[kshunter]

I dont know a whole lot, but the basics. My.dads the guy whos pretty into this stuff.

I think from what kshunter stated his 2040 is above SN 349999 because he stated his tractor had an electrical speed/hr meter therefore the wiring will be different than what's in the TM you're referring to. Correct TM for later model 2040 is TM1221

 

[kshunter]

Yes, a rpm gauge, fuel gauge, oil temp or psi, and a few other things I think.

Ah that would explain the extra wires. My TM4300 is from 1977, it has both hydraulic systems but only one electrical section.
