Turn key on, observe blinker closely.  If it blinks for a couple seconds,
stops, and then starts blinking again a few seconds later, the coolant
level controller is triggering and causing the blink.

If blinking starts with key and does not stop at all, verify ten volts
plus/minus half a volt input to the gauge (between skinny ground pin and
whichever of the other two gives the higher reading).  If voltage is
correct, continued blink is caused by leaky 10 uF 16V capacitor inside
gauge.  Replace cap or gauge.
