Lights dim at idle
when I am driving around, basically off idle the voltage is at 13.5. When I idle the voltage drops to 12.5, which i read from searches that is normal. The annoying problem is that at night when the voltage drops to 12.5 you can notice a slight dimming of the headlights and dash lights. Can this be corrected some how?
thanks, phil

I do not believe the voltage should be that low with the engine idling. Sounds like the source of the problem.

I see this every day on motors much newer than our cars, personally as long as they go to "normal" illumination as you rev up, i wouldnt worry.
