How To Install Club Car Precedent Brake Light Switch Diagram So.it certainly appears to me that the brake relay is the culprit. I shorted out the brake pedal pressure switch and the brake lights still did not work so I do not think that circuit/switch is the problem. I put everything back together and the brake lights do not work, again, although everything else still works normally. I fiddled with the switch and actually had the brake lights working normally. I measured the coil resistance and I believe it was/is? in the 2K vicinity.
I confirmed with a VOM that the NO contacts are open. I also found a nice schematic that shows that the orange and blue/white wires go to the coil and the green/white and blue wires come off the NO contacts. I have a Precedent Maintenance and Service manual and the wire color codes match exactly. Two of the terminals are labeled com and NO.
Orange, Blue/White, Green/White, and Black. I located the brake relay behind the 'instrument panel'. I have checked that out and with foot pressure applied the circuit is completed, and the brake lights should go on. The brakes are actuated by a small pressure activated strip switch that has been inserted just behind the rubber brake pedal pad. Everything is working OK right now, except the brake lights. Headlights, brake lights, horn, tail lights and turn signals. My 09 Precedent electric has this lighting system installed.
Replacing the relay fixed the problem since my pressure switch was ok. If it works normally then the relay has failed.in my opinion. If it never opens when pressure removed it has failed. Do the VOM thing on the two leads off the pressure switch to see if it closes/opens under pressure. My brake light switch is of a different style, but is also pressure activated.
