🤔🤔 Had to Google the vacuum switch that George mentioned and it looks like he is correct. Having never had a stock Cleveland in 2511 the photos didn’t ring any bells for me.
Granted, it shouldn’t be connected to the temperature gauge but if he has followed the wires to it then maybe it is, in fact, the problem?
I think Chris needs to do some more discovery research.
And take pictures and share them with us.
