With the key in RUN, check that wire for 12V. If it's dead, my next guess would be a burnt bulb in the cluster. Use the Haynes manual wiring diagrams to see how it's hooked up.Steve83 said:The dash light should come on if you turn the key to RUN & short the switch's wire to the brake mechanism chassis.
well, the bulb will come on when you start the truck, ya know, when all the lights come on. so i should see if the wire has 12 volts, and that means the light would be off?? and if the wire has no volts, the light should be on??Steve83 said:Did you not try this???

:shrugSteve83 said:...then try grounding it.
If it comes on when it's grounded, but it doesn't come on when you press the pedal, and the pedal ONLY allows the switch to ground it, then the switch isn't grounding it. Fix the switch. It's either dirty contacts, or a weak spring, or some kind of mechanical interference.Steve83 said:The switch...contacts are exposed, so ...clean them.
