How many volts does your vette run?
I noticed tonight while it was idling the lights would flicker. It said it was from 11.9 to 12.3 volts. I put a new alternator on it last year. Does this seem kinda low?

Battery Voltage
I had a similar prolem with flickering HVAC and radio displays. My battery voltsge was also jumping all over the map from 12.3 -- 12.8v. I found that my positive battery cable was loose. I tighten the cable, and the voltage reading on the DIC now ranges from 13.9v - 14.1v.

Just had the same problem (low readings). Tightened the positive cable-reading at 14.1 now

My DIC and hand held volt meter both read 14.2 right after start-up and if I check it after coming in from a drive it is usually 13.8 or 13.9. It really does not deviate much from those numbers.

I get that same error message sometimes when I start my car. Not everytime. My car starts fine however but that message does make me a little nervous. At 65 mph and driving steady my volts range from 13.1 to 13.4

Is the optima battery the way to go?
Is the Optima battery the way to go or is there a better battery. Also is there such a thing as a gel battery? Someone told me about it, or is the optima a gel bettery?
