I'm forwarding this for club member Mike Hassenplug who lives in Kansas. He is not able to post on the list server. Bob Merritt, I've also sent this to you so that you can add Mike to the server.
I'm not that versed on electrics. Here is Mike's post to me.
The needle on my temp gauge on my 300 B jumps around like a rabbit on meth. Sometimes on the highway, it'll settle down and perfprn properly, but it'll go back to being spastic again. I suspect a wire, but the wire from the temp sensor appears ok, and it appears to go to the generator. Can you refer me to someone who could help?
