2005 Corvette the Voltage is 14.2 when started, after a while the voltage drops down to 13.7 sometimes lower is this ok. Should the voltage be 14 all the time.

If the battery is fully charged it could drop as low as 13.3 or .4 .Do you see a brightening or dimming of the HL's at different eng RPM's?

No dimming. Just thought it was to be higher than 13.3 or 13.4, new battery. Thanks

Depends on the typ of battery. AGM will read lower sometimes down below 12. I was running an Optima battery it drove me nuts.
