82 hours on B2650 with loader. Started blowing key stop fuse randomly without any pattern. Sometimes runs 30 minutes, sometimes 5 minutes before it blows. Have tried to trace wires to no avail. any help would be greatly appreciated

I believe that model has an issue with the hst pedal switch shorting out and blowing the fuse. Ill see if I can find the thread(s)

Attached a link to a thread I replied in regarding the trundle switch replacement.

I haven't had issues with fuse's yet....but that switch was sure annoying.
Go buy one and have it ready for when it fails. I picked up a spare!
Kinda like having a 7.5mm ready when you think you can get a 8.0 tube as back up!

If its not related to the hst, it may just be the stop solenoid. The windings go bad and they get hot absorbing too much current.
It is located by the injection pump.

I had a similar problem with my B2650. check the ignition switch if it's loose the switch could rotate and short out against anything metal behind the plastic cover. it's just a matter of repositioning the switch and tightening it if that's the problem good luck
