Temp gauge
Doing some work a few weeks ago, my temp sending wire got smashed. The gauge pegged out all the way to the right but engine was not running hot. I found the cut in the wire tonight and fixed it but the gauge is still maxed out. Will this correct itself or do I have to do something else to get it showing correct temp again?

It sounds as if your wire is grounded somewhere.
When the wire to an electrical gauge is grounded the gauge will read all the to the right (Hot).
Take a close look at the temp sender wire and verify that it is not touching metal anywhere.
Good luck,
Jeff

I had the same problem with my 77. Replaced gauge, sending unit, and wiring. It still pegged when I turned the key on. Today, I went for a drive of about 40 miles and noticed that the temp guage, while pegged, seemed to bounce slightly to the music I was playing. Got home and checked the ground on my stereo - it was grounded to the standard wiring harness ground. Changed the ground on the stereo and now the temp guage works. I don't understand but am happy.
