My GT5000 starts and runs fine for 30/40 min and then completely dies. Will not even turn over. Electrically dead.

If I remove and replace the 30 amp fuse under the cowel it will start right up and run for a while before this happens again.

When I remove the fuse the socket is extremely hot. The fuse does NOT blow. Very odd. Any ideas on what could be going on here?

Welcome to the forum. My guess would be a bad connection at the fuse. This will create heat and not blow the fuse. As it heats up it can also take the tension out of the connector and lose contact causing it to quit. May be time for a new fuse holder.

Welcome to GTT. I agree with above. Intermittent electrical problems can be very difficult to figure out. Be patient. Good Luck, Rick

If the fuse holder is getting hot, it's probably corroded enough to cause a bad connection. Or the wires may be just too small, Are you using an electric PTO clutch? They draw a lot of current. One other question, why a 30 Amp fuse? What does your tractor have that draws so much power? Is that the stock size fuse?

 

Ok several other questions. My bad

Thanks for the replies. Yes this does have a PTO.

Although the owners manual doesn't spec the fuse size, the original was 30 amp.

When I remove the fuse (I have replaced it a couple of times) it is showing some sort of deposit on one tang.
Flipping it always results in the engine starting. I think I agree the socket may be bad.

30 amps is a lot of draw for anything on a GT. 30 amps would be adequate protection for a 20 Amp circuit.

If your PTO is pulling that much, I'd be worried about that. If you still have the problem with the PTO off, I would suspect a short somewhere.

 

 The deposits are likely from arcing due to bad connection.

I think mine has a 30 amp fuse also Everything electrical goes through the fuse including the charging system.

The only thing I can think of, that would pull that many amps , other than the PTO would be the starter solenoid, except for possibly the intention is to protect the battery from the charge circuit.

Update.....

Went to Advance Auto Parts. They have a replacement fuse holder including one 30 amp fuse for under $4.00.

I couldn't see what I was dealing with until I removed the battery to get some room and cut out the old holder. Had to cut quite a few zip ties to get to it.

One side was pretty much burnt up, must have been arcing quite a bit. Grafted in the new fuse holder and ran the tractor for about
an hour and a half with no overheating. I was able to move the fuse to an area where I can inspect it as I'm operating the mower.

Thanks a ton for the help. I agree that electrical gremlins can be impossible to track down. I needed confirmation that it made sense to take the cowel apart to work on this problem.

Now we just need a picture of the girl in action.

I have a GT5000 and it has been a real workhorse.
