Hello, I am the latest owner to suffer this intermittent starting problem, which has gotten worse over time. I have a TC-29DA. There is a LOT of information on this site about the issue, and a good bit of it very useful. I believe, as of yesterday, that my problem is resolved (5 strong starts so far, hot or cold, without issue yet). I applied the starter relay circuit fix and cleaned up a few connections along the way. In total, I:
1. Added the starter relay circuit described (post #51 on this thread) <-- I suspect this is what really solved the problem
2. Replaced the positive battery cable end (resolved the OP's problem, and I thought mine looked pretty worn anyway)
3. Cleaned terminals on all fuses and relays (and replaced one fuse)
4. Cleaned ground connections to frame under battery and under starter
5. Cleaned ignition switch terminals

Lately it just clicks when turning the key. I can cycle back and forth with the key and it will eventually start. I believe its the solenoid. The cost of a new solenoid alone is twice the cost of this unit Amazon.com: STARTER MOTOR NEW HOLLAND TRACTOR TC29 TC29D TC29DA SBA185086551...

My TC-29 sometimes will not start. The Ignition light comes on but no start. A click sound in the switch is it. Sometimes it starts, sometimes it doesn't. I have had this same problem off on on for several years. I have replaced the battery, the battery cables and have had the starter and...

On our TC40D we have a starter problem. Sometimes it will only "click". After several attempts with the key, it will start. We thought "solenoid". We pulled the starter and took it to someone we know who has fixed starters and alternators for 40+ years (it is his business) and he did find...

I have been plagued by the starter solonoid clicking now for about a year and have read the various post by others at this sight. I did not experience a blown fuse. Today I installed the 30A relay that others have reported using to fix a low voltage problem and the starter comes to life like...

(I said there is a lot!)
I purchased all materials needed at NAPA. Here are the part numbers as of today:
Relay: ECH AR143 (match for the three Bosh relays on the RHS of tractor for the glow plugs, neutral safety, and PTO safety), $20.69
Connector: ECH EC23, $ 14.33
Fuse holder: 782-2023, $3.88
I did not have the proper sized ring terminals, so I bought two packages (20/15 count) to get the two specific sizes:
5/16" blue ring: 784336, $5.99
3/8: yellow ring: 784348, $5.88 (they did not have blue for 14 AWG wire, so I crimped it good)
The connector has approx. 8in wires for each terminal, so no extra wire was needed for the job. The connector came with the butt-end terminals to join the wires. Everything listed was all the materials used (plus a 10A fuse and a mounting bolt). The day I went to do work on this, the tractor did not start at all, so I did it with the FEL attached. That was not pleasant, and my fingers hurt later, but it can be done! My wire from the neutral start relay to the s-terminal on the starter solenoid was tan, as indicated on the TC29DA/TC33DA operator's manual. I grounded my added relay to ground bolt below the starter. Getting at that area around the hydro manifold was the most tricky part... patience and luck.
