No start S175 bobcat

No power to panel when key turned on. Checked fuses and found an alternator fuse blown. Replaced it but there is no power to either side of the fuse. Checked for a short throughout the wiring and nothing found. Pulled alternator and had it tested at a shop. Tested good. Must be a short somewhere. Pulled panels off and checked wiring going from key switch across all ok. I did find the computer fuse blown and changed it and on my display it reads "Input" cannot get any error codes. All the relays test ok and power to all of them. I talked to a Bobcat tech and he told me "Good Luck" and if I find the problem to let him no ! wtf !

last "input" code i fixed was a bad controller. it was 750 for controller and you need a tech with service analyer to program computer. Do you have a 7 pin connector by your aux. couplers. if that harness end is smashed or the harness is pinched it can also give this code.

Check for continuity between wire 9100 on the controller to 9110, left panel. This is computer power. Also you can check continuity between 9100 and 9120, right panel. Sounds like the two panels aren't communicating with the computer. ( Broken /worn wires)
