I performed a search before I posted the thread and nothing came up to address the problem. However my spelling skills are lacking. From what I gather about the sending unit is that if there is a break or fault in the wiring the gage will peg out at the left hand side (cold). If the unit is bad or dirty it will peg out on the right hand side (hot). I will try to disconect the wire tonight to see if that has any effect on the gage. And then I will replace it just in case. If I can figure this out it might be good info for the website. Thank you for the link to the other thread.
