ruralandalone Posted January 1, 2020 Posted January 1, 2020 I picked up one of those plug into the cigarette type voltmeters for my 86 Comanche. I was surprised to see that the voltage seems to be averaging over 14.5 volts, with an observed high of 15.1 volts. Is this unusual? Is it a sign of an impending problem that I should address? I know the battery is good, and fully charged.....
Ωhm Posted January 1, 2020 Posted January 1, 2020 12.6vdc battery, 14.7vdc alternator, that makes for 2.1vdc charging (counter) voltage for the battery. Normal
ruralandalone Posted January 3, 2020 Author Posted January 3, 2020 Thanks for that! I thought it a bit much, but that is why I asked.
ghetdjc320 Posted January 3, 2020 Posted January 3, 2020 I run an external voltage regulator and keep it set to 14.5. Works great and gives plenty of power to my electric fans and headlights
