2001 NH TC35 starting problem

[Keebler]

I have seen more then a few problems posted with the TC35 starter problems. I just bought this tractor with known starting problems. Turn the key and all the glow plugs work as it should but there is no turn- over of the engine after. There is now click or anything. The previous owner had been using a jump wire on the starter/ solenoid to get it started- it turns over and starts fine with the wire. I changed the key switch out when i got it home in my garage and nothing improved. Im looking for some ideas or knowledge on what i should do next. I can get it going- i just don't want to rely on the wire.
Thanks for any help?..

It's likely a safety switch issue or wiring problem in the safety circuit. Check all your safety switches (PTO, transmission and seat) and the wire along that path and you should find the problem.

I got tired of fighting with mine and added a push button to a circuit that is powered by the ignition key and goes straight to the starter, bypassing the safety circuit. Not the best solution but it works 100% of the time.

If you have not read through the sticky on NH starting issues you need to.

I sold my 2001 TC35 last spring and it had intermittent starting issues for the previous 3-4 years. Such a pain. If I had it now I would do the wiring modification listed on page 5 & 6 of the linked thread.

I found that post last night. Im not real confident in my mechanical skills but I'm going to start with the fuses and look at the relays. Maybe put in one of the breaker type fuses. The new wiring looks promising though. The tractor seems to be strong otherwise.

Thanks for the help. I just need to wait until its not -15 degrees outside to work on it.

Well, it's good to make your plans and get your parts around anyways.

It seems like there could be multiple issues with these machines. At least multiple solutions. So many people with starting problems. Go to Google and type in the following.

The search within this site is horrible. Google does it much better. You will see there are many many threads out there. You might be able to glean some info from some of them too.

While the fix in this thread is a good one, I don't think it's going to solve his problem because he says he's not getting a clicking sound. To me, that says that no current is making it to the starter solenoid so it's probably a safety switch or otherwise broken circuit.

That could very well be.

I'd also say to check the fuses. Mine would always blow fuses after having an unsuccessful start.

I think that was one of the symptoms that the linked fix was supposed to help.

Any further information that Keebler can provide when he starts digging into them issue would be helpful.

I feel like just by-passing the whole safety interlocks……
I looked at the fuse box- its caked in dirt. I need to find a good way to clean all the contacts. The local auto stores didn't have the right size circuit breaker for fuse position 2. That should be in tomorrow

A quick way to visually see if the fuse is blown is if the PTO indicator light is lit up on the dash even though it's fully disengaged. When the breaker trips, the PTO light comes on and it goes off after the breaker resets.

Although I did it myself, I would not recommend bypassing the safety switches. At some point, I'll probably fix mine correctly but for now, I had work to do and needed a quick fix.
