SC2400 5 amp meter fuse keeps blowing shutting off tractor

[Yard2Big]

I have a 2008 SC2400 with 300 hours. It keeps shutting down and I thought I had a fuel problem but found the the 5 amp meter fuse kept blowing and shuts the tractor off. Has anyone else had this problem? Any suggestions where to start troubleshooting the problem. After changing the fuse, tractor will start and run for about a minute then fuse blows again. Not sure if it's a relay problem or wire short. Wire harness is not easy to get to. Thanks for any help.

Thank you for the manual. I'm going to try tracing the wire from the fuse box and see if I can find a short. Will start by disconnecting the first connection I encounter then turn the switch on to see if fuse blows. If fuse is OK then move to next connection. Hopefully I will be able isolate the problem area. Can't follow all the test procedures in the manual because the fuse blows as soon as I turn the key to the on position.

Mine turned out to be a relay. It was the relay on the right side up under the dash shroud above and to the right of the battery.

My tractor shut off 2 times today, is the relay that you replaced blue? The markings on it are: H3A-DIE G341AL with symbols of diodes on it.
It was the only thing I could see that was above and to the right of the battery.

If it is under the dash, there are two relays on the right side of the battery, on the right side there is the safety relay for the HST and the one next to it is the safety relay for the seat. Which one did you replace or both.

Where did get the relays?

My guess is a chaffed wire somewhere.
