My sensors are failing Coil,oil,brake and now the engine temp

also replaced the seat bar sensor and now it reads 12-23,7-11,6-11

Just a guess here but would look for a bad ground

May also want to check what the charging system voltage is when it's at full throttle.

I checked the grounds, I checked the alternator at the battery and it was 14.57

Mouse nest?

I have ran thru the wires several times and have yet to spot any damage. After replacing the sensors the codes have been removed, however the loader locks up and will not move and may show NONE or several other codes

Did you find all of the grounds some are hidden and don't forget the main one off the battery

I'm not sure if i missed any hidden grounds. I did a test with a volt meter,, positive side of the battery positive side of tester negative side of tester to positive feeds and it shows a positive wire grounded. Would a coil or sensor not working create a ground?

This is still unresolved,, I checked and cleaned all the grounds i am aware of, replaced the computer,wiring harness and the key switch ( they were badly weathered) all the sensors and now the temperature gauge fluctuates and locks the loader.

Have you tried disconnecting the alternator to just check that it is not over voltage? very odd issue

I had the alternator tested.

Maybe it is getting warm but not over heating, the erratic gauge is baffling

Loose or bad connection on gauge or sender clean and check fuses and relays
