Subject: 6410 blows fuse while driving???


Central Arkansas		It blows the first fuse on the top, left corner. It's fuse F101. It happens while I was driving to another farm. The tractor just died and I coasted until I came to a stop. I got off, wiggled the wiring harness that runs to the fuel solenoid. I put a new fuse in and made it a quarter mile and it did it again. Anyone have any ideas what to check. Could it be a sensor going bad?

w pa		I hope someone replies with an answer for this, I have a 7410 doing almost the same thing runs till it gets warmed up then blows the key switch fuse and dies, but mine will keep blowing fuses till it sets for a while and cools off, replace fuse starts up and goes till it blows again.

middle ga		May not be related but my 5075E was doing something similar. There is a sensor located in the thermostat housing that when it goes bad will kill the engine. It is tied into the injector pump somehow. Mine was blowing a 10 amp fuse. I have had to replace it twice. If you can find the plug you can jump it out to get it home. I did. Hope this helps.

This a cold start sensor.

Could be this if it has one.

Mid-East Nebraska		It could be the cold start sensor, had a few irrigation engines that blow the fuse when it got warmed up, until it gets warm the injection pump is on cold start and then the sensor changes the injection pump to run normal and that is when the fuse blows because the sender grounds out. Look at hte pictures it is on the thermostat housing.

I think Tom is on the right track. Had a 6410 do the exact same thing back in the day. Don't have it now, so can't go look at it. However,in my case, it wasn't the sensor in the thermostat housing, but rather the solenoid on the injector pump. (IIRC, the sensor in the thermostat housing was connected with this solenoid. It was called a cold start advance(solenoid) or something similar. Tractor would run fine cold, but would blow a fuse and shut down as soon as it warmed up. (This was about 5 years ago, so the details are getting fuzzy) IIRC, the solenoid was at the end of the injector pump toward the cab, and was in a vertical position. ( Had a small stud and nut with two wires??)

If someone would post a picture of the injector pump, l could point it out. Sorry for my poor memory!!

Hope this helps, post back with your results!!

Good luck!

Northeast Misery		Wiggle every wiring harness, while looking for bare wire and pinch points, find nothing. Take dash and ignition apart, find nothing, and put dash back together.


Had this problem last August, hasn't missed a beat since. ???

Most likely the cold start advance sensor. We have replaced many of them over the years. Just unplug it at the thermostat housing and drive it. If fuse doesn't fail, replace sensor when you get a chance to.
