Loader New Holland TC35 FEL wont start?

jinman · Oct 22, 2012

When the engine turns over but refuses to start, it's normally a problem with the seat switch or you do not have the Range Lever in neutral and the Parking Brake set. If you have both of those, then you don't need to be in the seat. If not, the safety system will not send power to the fuel cutoff solenoid on the back of the injector pump.

Alright so far heres whats going on, I disconnected positive batter cable and used jumper cables only one side on positive to positive on starter and reading 12.5V. even when I turn the key on still has 12.5v. before just hooked up w battery normal readings dropped to 3.5v. so I think I have a bad positive cable. but it still doesnt turn over. so I kept the jumper cable on starter and battery, with a jumper from plug on starter to the starter while having the wire disconnected to the back of the fuel pump but replaced with a wire long enough to reach the batter to the back prong on the fuel pump and while jumping starter she started right up. So I have a bad safetly switch either the parking brake or PTO or transmission, I do not have a seat switch? I cant find it anywere? but still working on it. might just get er running enough to put on trailer and send to dealer. uhggggggggg!! Ill keep ya posted, thanks somuch for all your help guys!

Alright guys! here it is! hope this might help someone in the future! looks like two problems happened. One losing voltage to starter when turning key is not suppose to happen so I disconnected batter terminal from battery and jumped with cables from battery to starter, then as I turned the key I did not lose voltage. which means bad positive cable! Then it still wouldnt start so I jumped the fuel pump by using a long enough wire to connect from battery to back of the pump, pulled off the wire connect and put on the wire hooked striaght from battery , then jumped the starter by disconnecting the plug on starter and making contact from their to positive on starter, then behold she starts! drove on to trailer to get fixed. Still dont know which safety switch went bad, but thinking it is the PTO or parking brake? Pain in the arse!!!

replaced batter positive cable, they couldnt make one up so they ordered one from factory! secondly there were a couple realays / Fuses that were acting up and then working then acting up , so they were replaced and better connections were made as well. Electrical problems will drive you freaking crazy. Not to mention that during the process of me diagnosing and taking the battery out to get checked, while putting back I accidentally made contact to the negative terminal and the positive terminal with a wrench in my hand touching my wedding ring and arched / welded the ring and burned the ***** out of my ring finger so bad, i lost muscle and now have a permanent ring burn that will take about 6 months to heal. real bad. EVERYBODY WEAR GLOVES WHILE CHANGING OR WORKING ON BATTERIES! Now the tractor is in perfect condition and I am selling now for anyone interested. only 850 hrs.

I had the same issue with my Case DX33. (Same as a TC33 NH) I actually melted 3 key switches.....but I had similar problems. Slow or no starting. I replaced the starter and the battery. Turns out, both were fine.

New Holland had a problem with the key switches. You need to install a relay between the key and the starter solenoid. Have the key trigger the relay and I used a 30a relay that was wired directly to the battery terminal. It's a pretty simple wiring thing to do and I'm actually thinking of making kits for it. The 5th page of this thread should be loads of help for you!!!

Im on my third ignition switch. First one stuck in start, the second one had some of the same problems as yours.

Do the relay. It is "THE FIX" for these tractors.

If you need help....let me know. I set mine up and it would be easy for me to do another. Just wire it in amd go
