GC1710 Temperature gauge

[Rocko]

The other day I noticed the temperature gauge stopped working on my GC1710.
Is there any way to test the sending unit or the gauge.

I assume you can use a digital multi meter on the lines hooked into the gauge to make sure you have voltage. Have you checked your fuses also?

The sender is right by the thermostat housing. I'm sure it works like a normal car temperature sending unit with high resistance when cold and low resistance when hot. Ohm it out and see what it gives you...

Thanks for the help.
Checked all the fuses, they were ok.
Resistance dropped on the sending unit after the engine warmed up.
Pulled the plug on the dash to check the continuity of the wire from the sending unit......had to wiggle the wire at the sending unit end to get a beep. I suspect a break in the wire at the connector.
I will try a new connector this weekend and report back.

Had some time after work today to work on it.

I cut the connector off, spliced in about 4 extra inches of wire.
I used a blue bullet connector since it looked like it was the same size as the oem connector for attaching to the sending unit.
Started the tractor.....the temperature gauge started working again.

Thanks again for pointing me in the right direction.

You should take pictures when you open up stuff so we can build a databse on stuff that been done to our tractors,

Good to know you fixed it. I will have to remember this if I run into the same problem.
