Have the Guage Pod installed. Did no calibration work to it. System is reading about 13.8- 14.0 Volts. Seems highish. Anyone else?

Never mind - digital volt meter and RD both call out the same voltage as the guage.

13.7 volts is the normal operating voltage.

normal charging system voltage on any vehicle is 13.5-15.0 volts, any lower and you have a weak alternator, higher would indicate a faulty voltage regulator in the alternator.
