I have a 1979 century with boat side original wiring. I repowered the boat with a 5.7 engine and thunderbolt 4 ignition. When I view my dash voltmeter it reads about 12.5 or so volts. If I run the blower with engine about 1500 rpm the voltmeter drops a bit. If I add lights etc a bit more.
I verified the accuracy of the dash guage with a digital meter. Then with engine running again I used the multimeter at the positive and negative battery terminals and find a healthy
13.4 to 14.0 that varies with rpm (all below 1800 rpm on muffs)
Does this make sense?
