I have a 5205 JD . driving with a load of wood and the tractor just stopped as if it were out of fuel. tried to restart it and it did nothing. found a blown key switch fuse , I replaced it and when I tried to start it the fuse blew again . It did not turn over at all. What is causing this to happen?

How was the load of wood being carried ?
Did you twist the tractor ?
Did anything happen while driving the tractor before it stopped ?
Are there any harnesses hanging ?
Were the lights on ?
What works now ?

You said key switch fuse, could it be fuel-solenoid, if so/would not hurt to try.
I believe the problem is the temperature sensor. On the thermostat housing there is a temperature sensor that is connected to a two wire harness that goes to the injection pump, this is the "cold start advance" portion of the system so it starts easier when cold, the sensor is so it doesn't activate once warmed up. If you disconnect the sensor and it works fine ohm the sensor, probably shorted.
The sensor on the thermostat housing, that controls the advance on the inj. pump. When it fails it shorts out and blows the fuse. Try unplugging it, replace fuse and see if it starts and runs. The part # is RE503242 (see picture), if you are quick changing it, you don't have to drain the coolant, just make sure it's not hot at the time.

Here is a URL on the 3029 engine and addresses the cold start

Some light reading for you. These things may not apply to your 5205 tractor, but it is nice to know if the problem should come up.

I went out to the tractor and pulled the wire off of the stat and it started, no blown fuse . You just saved me a lot of money! I'm sure the dealer would have found something else that would have cost alot more to fix. I will take the savings and buy me more 30 amp fuses, I used all that I had. lol THANK YOU VERY MUCH You guys save us guys alot of time and money . I'm glad we have this site to go to .Thanks again

I had this same problem and this thread got me back on the job. Mine was the temperature sensor. THANKS!

Ours was the temperature sensor. We just unplugged it and replaced fuse. Other fuses good but while tractor runs fine now none of my gauges work. Is this normal while operating with sensor unplugged?

The temp sensor went out on my 5303, gauges still work unplugged. New sensor $48. I've never needed that garbage on any other tractor to start:confused3:

Being a former JD dealer service manager it's difficult for me to understand why JD hasn't corrected the temp sensor that's had a history of failing since the mid 90's when the 5000 series tractors were introduced.:confused3:
Looking at the operators manual link to the manual include, the instrument gauges and fuel shutoff solenoid and sensor are on 2 different circuits, so unplugging the sensor should have no effect on the gauges. It would not hurt to double check the red 10 amp fuse.

Here is what the tech manual for the engine states as the reason for the sensor. To comply with the exhaust emissions regulation, the timing of injection pump should be around 6 to 9 degrees before TDC. These timing values do not allow proper start-up operations when engine is cold. To ease engine start-up, a cold advance system gives to the injection pump a temporary over-timing.
When coolant temperature is below 50 C (122 F), the solenoid valve is activated and opens the cold advance circuit.

You have to wonder how all our older tractors ever started w/o that junk on it:laughing:

Thank you for posting the pdf. I wonder if I'm the only person that didn't have a clue how solenoid accomplished the IP timing change?
