No Idiot Lights
When I turn my key on, I only get a GEN light. The temp, oil and brake lights should be on , but are not. {'69 base, 327)
I removed the instrument cluster and checked voltages there. I ruled out bulbs and the circuits on the cluster. When the key was turned on, I had voltage at the plug for the GEN light, but not the others.
None of the schematics I have are detailed enough to figure this out. Is there a component which is common to all three issues?
I can't tell if the lights work under normal conditions. There was an aftermarket oil pressure gauge when I purchased the car, which shows good pressure. As far as temp, I have no indication, which scares me. I replaced the water temp sensor, no change.
Any electrical gurus out there?

Oil light - if Camaro originally had idiot lights, the pressure sensor is a switch once 5 PSIG is generated - switch opens and turns off the light.
Since you say an aftermarket gauge is installed, most installers would have installed a 'Y' to keep the switch and provide a port for the oil tube to gauge. Easiest install is to install pressure and leave oil light wire tucked away.
Temp light - again, comes on when ign key is in START position. Temperature switch this sensor is and by maker's design, usually comes on at 256°F.

I'm not sure what you meant by this statement. Are you saying the sensor is the switch? If so, I already swapped the sensor, and had no change. Maybe I need to check continuity in the wiring harness.
Thanks for your feedback!

I understand that the temp switch will turn on at 256, but shouldn't it also light up when I turn the key on, to test the circuit?
If the light is not supposed to come on, I'm troubleshooting a system that ain't broke. I will trust the new sensor I installed.
If it is supposed to come on, I have an electrical issue, and can't assume the light will come on when needed.
I just need to know if it is supposed to come on when I start the car.
