My lights all seem to run a little dim, i put this down to it all being old. But im wondering what effect an old tired voltage regulator might have. i have a 68(C-4) with console shifter, the kind that has lights in it to tell you what gear you are in. When i use my turn signal the lights inside dim with the flashes.

Would this affect my dash gauges? I have a coolant gauge that says i run cool, but i think the engine is running pretty warm. I get vapor lock after long runs and it seems pretty hot.

so can anyone tell me what the voltage regulator does?

Thanks

Well the voltage regulator maintains the proper voltage to the battery and electrical systems at all time should be between 13.5 and 15 volts dc. Mine runs a 14.5 volts at idle. As for the effect on gauges i do not know but there is a constant voltage reg behind the dash that might be bad. Maybe somebody else would shed some light on the other problems. Sounds like a short on the turn signals, check all the grounds.

It's probably due more to the age of the wiring. As the wires and connectors age, they corrode and carbonize, witch increase the resistance the wires have, making your lights dimmer.
