temp gauge stubborn
I have a 67 with a 350. Temp gauge is buried over on hot. Have new wiring harness, grounded the cluster, grounded temp gauge to cluster at bottom post (6:00 on the 4 posts). Gauge did work before new wiring harness. Printed circuit board appears to be ok.
Any ideas appreciated. ![]() |

Re: temp gauge stubborn
Here is how the gauge is wired and it appears that you have it correctly wired.
The symptom you have is caused by the temp sensor green wire being grounded at some point between the sensor and the gauge. If the sensor is grounded internally it will also read hot.

Re: temp gauge stubborn
Oh, Uh the 90 ohm ceramic resitor seems to be missing. Maybe that could have something to do with it.

Re: temp gauge stubborn
Yes Sir - an open resistor (or missing in your case) will cause the gauge to read hot. Don't ask me how I know - lol.
