I have a Deere 240 skid steer around 2000 model that blows a 25 amp F1 Accessories fuse as soon as it is inserted. The machine runs fine but does not charge, no lights, etc. because of the fuse.
I have tested the relay for resistance, and swapped it for another one. No change. Relay seems good. Seems to get a little warm just sitting there.
I measure 12.3 volts across the blown fuse. This goes away only when I unplug the relay.
No other fuses have voltage across them with the key off
I unplugged the fuel injector and no change to this voltage reading.
New alternator.
Unplugged the alternator resistance relay, no change.
Any ideas? I have a service manual.
