Reply to "Seeking advice regarding how to trouble shoot a temperature gauge that doesn't work."

So sorry , I thought the pictures posted of the EPVS not EPS were of your car.

Going off topic ( oil temp gauge ) I thought that I had the EPVS switch - valve figured out but looking at the diagram of it I am confused. The diagram shows the retard side connected to manifold vac and the advance side to carb / ported vac. How's that work when carb vac is less than manifold vac ? I thought it was meant to advance the timing when at a high temp idle. For that matter how does the vacuum advance ever advance with the retard side constantly connected to manifold vacuum ?

Getting old sucks
