John Deere 4100 Blowing 10 amp Fuse when PTO Engaged

[DFB]

I think may be your direct shorting a wire with movement also as it happens after your started and moving.

My shop manual shows all these circuits (HST) are protected by the F2 fuse
BR1& BR2 terminals on key switch
Glow plug module
Glow plug relay
Fuel relay
PTO switch
PTO relay
Fuel gauge
Oil pressure light
Coolant light
Parking brake flasher
Light switch
Seat switch
Gear range neutral start switch
Rear PTO selector switch
Control module wiring

The gear model is pretty much all the same except for PTO neutral light relay and PTO neutral start switch

Hi, 8 years ago, but hoping the cause was found. I have a similar issue.
