I have a bobcat S150 and have a problem with the 25amp fuse for the Computer. The fuse keeps blowing even when the key is not switched to run, no lights on any of the panels and no wiring diagram, any ideas/
Make (other): BOBCAT S150Model: * XXXXXXXXX
Tried changing fuses, but fuse panel on computer fuse keeps sparking and burning.
Sounds like you have bad short, check your wires for any rubbing or chafing against metal. If the key is not turned on, it most likely would be battery power blowing the fuse.
Google your machine make and model include service manual in the search. you should be able to download a wiring diagram for you machine.
As a precaution disconnect your battery to stop any further damage until you find the cause.
Let me know how you make out.
