Foton 404 starting issues

[nyhillbilly]

I have a 2003 Foton 404. Other than normal maintenance issues, batteries, adjustments, etc., I never had any issues. The tractor was dependable, firing right up everytime I needed it. Parked it 2 weeks ago, went to start it today for some spring work, and nothing. No click, no anything. Battery testing good, power to starter, power into ignition switch. I even jumped across the starter terminals and the starter motor spun, but nothing at all when turning the key. Electric to all the lights and dash, I hear a relay click, but does not try to start. Any ideas as to what I should try or focus on next? Like I said, this machine has never given me any problems. I bought it new and am the only owner. It is almost time to get working in the fields, so I have to figure this out.
Ran fine 2 weeks ago, parked it, now nothing. Any ideas?

Key switch? Clutch switch? They both fail all the time.

There are two wires that feed the starter, the thick one that comes from the battery and the thin one that comes from the key switch. The thick one should have 12v at all time, the thin one when the key is turned. If you're not getting 12v follow the path back through the key, the clutch and the fuse box to find out where you're losing it.

The other thing to check is the quality of your ground connection. Measure that you have 12v between the positive battery terminal and the frame. While someone is turning the key measure the voltage between the negative battery terminal and the frame of the tractor. If it's not negligible you have a poor ground.

Found the issue. Plastic quick link underneath for the clutch safety switch had rotted and fell apart. After replacing the connector, tractor fired right up. Thanks for your time and advice.

And don't forget about the hungry critters. They just love the taste of that Chinese wire and hose.
