Bobcat T-190 8 volt power supply

[Mark Payne]

I am getting multiple codes for sensor faults plus 47-22 for 8 volt power supply. If I check voltage at seat bar sensor , oil pressure sensor and coolant sensor I get 2.7 volts. Grounds are good, removed and cleaned battery ground, ohmed wires between sensor plugs and controller...all check OK. I have wiring diagram but it has very small and poor print.
What else, besides the controller, could cause me to not get 8 volts at the sensors....or should it be 8 volts?

Dunno about Bobcat, but low voltage on a sensor line usually means a shorted sensor, try unplugging one sensor at a time and watch to see if the voltage comes up. Low voltage will usually cause all the sensors on that supply to throw fault codes.

Thanks. That would be better than a grand for a controller. I'll try tomorrow.

Hello my bobcat is showing H4741.
Can someone help me understand what's wrong with it or how I can fix this. It's powered off twice.
