You need to study the attached info. Your fuse blowing surrounds the safety switches and Operator Presence Controller. OPC.

You want to really carefully check the wiring around each safety switch looking for somewhere the insulation has worn through. The last and most expensive step is to replace the OPC.

As a test remove the #7 key stop solenoid relay and see if the fuse blowing stops. The engine wont start but it is one more thing to rule out.

Read the last post in the following thread for what another B2650 owner found to be blowing the 5 amp fuse.

I'd bet on the neutral safety switch. My dealer keeps a box full of them behind the counter.

I've only had to replace mine once. So far...

Exact same thing with mine too. Bad neutral safety switch.

I have a similar issue. If i set the parking brake with the machine running it will blow a 5 amp fuse and the display on the dash will go dark and no crank. If i release the parking brake and replace the fuse all is good. I replaced the safety switch and still have the same issue. Then i pulled the dash cover and replaced the fuse with a breaker, wiggled all the wires and got everything to work correctly, Great !!! so i thought now the next step was the wiggle each wire individually until i can consistently get the temporary breaker to pop. Never able to accomplish this , put it all back together and now fast forward 6 months and its doing it again

My 2650 wouldn't start after I shut it down to get off of it for a minute. I jumped the seat switch didn't work. I read to rock the HST pedal to make sure it was in exactly neutral. She started right up. I have since lubricated all the mechanical joints from the pedal to transmission. I believe there were 4 or 5 of them! worked the pedal back and forth to make sure there was no binding from corrosion or dirt. She snaps back to where it belongs now. Makes sense you wouldn't want the tractor to lunge forward or backwards upon startup so she locks out.
