There are two electrical parts to the coolant light circuit. One is the
coolant level control module on the fuse panel and the other is the
instrument cluster itself.

When the ignition is first turned on the light should blink for 10-15
seconds as a bulb test. This control is entirely on the cluster printed
circuit.

On an '84 the coolant level control module should be connected so that low
coolant both turns on the light and pegs the gauge. If you are only getting
the light then the printed circuit board is defective. Most likely the
timing capacitor is bad.

Hi;

I just got my daughters 84 on the road and have a pesky flashing
coolant light. Coolant level is fine. Operating temp is fine but the
light flashes. I attempted to loop the circuit at the bottle plug but
that pesky light just keeps on flashing. Ideas?
