Ford 6610 temp gauge doesn't move

[Srice798]

I have a mid 1980's ford 6610, noticed last time I ran it, temperature gauge doesn't move while driving, stays cold, replaced cluster panel, thermostat and sending unit, no change, any ideas

Is the sensor wire complete from point A to B. You are going to have to get a multi meter and check resistance when tractor is cold and hot and see if there is a difference. High when cold, low when hot. Do you have power going to your temp gauge?

Thank you for replying, going to check and run new wires tomorrow

Before you start running new wire check what is already there
Disconnect the wire from the sender and ground it with the key one, the gauge should move to full hot
If it doesn’t move pull the cluster out enough to connect a jumper wire to the sender side of the gauge and to ground, if the gauge moves you have a wire issue, if it doesn’t move check to see if you have power going to the cluster
You could have a blown fuse or bad ground to the cluster

I also find new knock off replacement clusters to require a different sending unit than the original one... as a fairly common problem... SO I prefer to stick with the old cluster if possible.
