Temp Gauge Dead
Irony - 23/8/16 at 12:28 PM

Driving to work this morning and my temp gauge was working happily. I buried the throttle and out of the corner of my eye I saw it drop to nothing. Dead. Now its not working at all. Tried the other temp sensors on the car and they are all working fine. Pulled the wires out at the sender end and joined them together. Nothing. Pulled the gauge out and the leads are all connected I think. Can't quite remember how its wired. I think just two wires to the back. Noticed some condensation inside the gauge this morning.

Any recommendations or is it new gauge?

Usual voltage checks ---- Powers & Grounds
With ignition on check the + supply voltage at the gauge.
With the ignition on check the voltage between a good ground and sender terminnal on the gauge and compare it with voltage between the sender and a good ground.

If its +ve to one side of the gauge and sender to ground on the other side, ground the lead going to the sender for a short time, the gauge should read max, if it does suspect the sender. You can ground the gauge connector to check if the gauge to sender wire is OC somewhere.

Tried this and still nothing, I'll have to get it out and try on the bench!
