86 325 w/ 64k miles.
Car runs great and does not over heat but the coolant temp gauge does not work correctly.
I have cleaned the posts and tightened the nut on the back of the cluster. I have also 'built up' with some solder on the board since it was a little worn out. I have also replaced the temp gauge with another used unit but still haven't gained on it.
SI batteries have been replaced and I believe thats where the problem is. Prior to the new batteries I had a erratic tach and MPG gauge BUT a WORKING coolant temp gauge.
I don't think the problem is at the thremo since it was working prior to the SI battery replacement.
Hints or info on tackling this?
