My temperature gauge on case ih jx100u not working and I can't find the location of the sensor. Any help greatly appreciated
I'm guessing it should be similar to the mx115 or use the same wire harness. If so then Both the coolant and the thermostat sensors are just behind and slightly above the alternator. Both are single wire blade connections so check to see if they have come loose.
Also check the fuse box to see if the fuse for that circuit has blown.
Its an Iveco engine same as New Holland TL90
