The temperature gage was working fine. Now it remains below the "C" indicator. I connected a wire to the
coolant temp sensor and a bulb to the other end and put it to the positive terminal on the battery. When the car
warmed up it dimmly lit.

This is an electric gage simply take wire of temp sensor and with ingnition on and ground it to the block or intake manifold if the temp gage reads full hot then the sensor is bad but if gage does not move then gage is bad. It's that easy "OLDSCHOOL"
if it starts keep it run'in for 2 hours,thencheck if the gauge is work 'in
