This thing only has one light for both? Anyway, it does not light up all, key in on position, or running. I guess that's why it had a rod out each side of the motor! Any ideas on wire diagrams? I thought it was a bulb out, but replaced it, still no warning light. I really don't want to put a set of guages in it.
Thanks on the wire diagrams! I thought when I changed the bulb, all looked good. It may be missing power to it? I take it the sensors just supply ground. I guess I'll check fuses, but everthing seems to work. I'll pull the panel back out and see what I find next, Thanks again guys.
Test the simple things first. Pull the cluster and put 12 volts to the circuit that runs that bulb, see if it lights. I have found that most older insturment clusters have one little sweet spot where the bulb will light unless you clean all the contacts. Just put power to it and turn it slowly till it lights up.
Just remove the wire from the sensor and touch it to ground the light should come on. If it does then replace the sensor. If it doesn't then you have a circuit issue that you will need to trace down.
