Temp Gauge Troubles
When I take the wire off the sending unit and ground it out, the needle moves 3/4 of the way across the gauge.
(I think this would indicate that the gauge is OK?) I also put in a new temp sensor between the #1 & #3 spark plug. I did not use teflon tape as not to interfere with the ground. Still the needle only jumps when I turn the key on and nothing after that. Any other Ideas that could cause my temp gauge not to work? |

Spliced Wire
The wire was broken so I spliced in a new one, I used a much heaver gauge wire however, could going from original size to large size back down to original size be my problem?

I have a question about the gauge. If you are looking at the back of the gauge, which post is the 12v and which one is the sender?

Possible Cause
I did a little more research...
I bought the sensor at NAPA they have the same part number for the light and the gauge sensor. I called a few other parts stores and they have two different part numbers and prices for the two sensors I guess sometimes even the experts can be wrong |

With the key off, both posts are dead.
With the key on, both posts are hot?...could it be my circuit board? |

another thing that it might be is they gave you the sensor for an idiot light dash instead of the gauge model. They do make a difference.

(I think this would indicate that the gauge is OK?) Actually the guage should peg on the hot side. I would check further into sender wire. Possible bad ga. also. Plus check sender # as was mentioned. John
