I have an older Bobcat that I use around the farm. It has not been well maintained but so far I've been able to fix it whenever it breaks. The latest problem seems to be a bigger challenge. It was running fine last week using it to move some cut down trees. I shut it off and when I went to restart, NOTHING. No indicator light, no beeps, no clicks. The only thing I get now is on the left panel it displays "INPUT". I have power to the starter. The ignition switch is working. I checked all the fuses (both visually and with multimeter to see if both sides had power) and they all passed. I swapped out the relays in the fuse box. Still nothing. I don't have a wiring diagram or repair manual so I am looking for advise on where to check next. I've checked other threads but didn't see anything with this problem. Any help would be great. I'm stubborn (aka-CHEAP) and don't want to have to haul it to a shop to fix until I've tried just about everything myself. Thanks in advance....

"INPUT" means the the left panel isn't receiving any signal from the controller(computer). Check the cable that connects them for rubbed spots and corroded conections.

If this is a G-series machine. Lift the cab, and check that the foam under the seat pan is not touching the controller harness. Could be worn wires? If U see an indent from the controller, cut out the foam. It shouldn't be touching. Again, check for worn wires, and connections into the controller
