Re: Temp gauge problem
It's wired wrong or grounding out I bet if new sensor and two diff gauges do the same thing.

Re: Temp gauge problem
It's the resistor on the back. Or more likely, the insulators that go in that area. If I remember, they are just like washers that go on the posts.
Did you have it apart before this started happening?

Re: Temp gauge problem
There should be a resistor on the back of the gauge between the top and bottom posts. Picture is attached.
I should have a couple of extras if you happen to need one. |

Re: Temp gauge problem
That is the cluster with gauges.

Re: Temp gauge problem
Different style, but same part.
Must be a sender, ground or other wiring issue. |

Re: Temp gauge problem
Could the resistor be the problem if the gauge always stays cold?
