Volt gauge reads a hair over 12 volts.....

[kozman01]

Is this ok? I charge my battery every time I return to the house. While I'm on the water, the gauge reads a hair over 12 volts, I'd say around 12.2 volts. Is this acceptable or no? Also, is it the rectifier that charges the battery? I'm only asking because I have a good condition used one. Thanks for all and any help.

What engine, Koz? Does it charge the batt?<br /><br />Sounds like there is no charge to the batt. <br /><br />If the engine is charging the voltmeter should read around 14 volts. A fully charged battery with no load should read about 12.6 volts.<br /><br />Good luck.

JB is right.. Between 14.1 and 14.7.. while running and 12.4-12.6 no load.

Check it with digital meter, dash mount meters get banged around a lot and might not be right.

These engines don't have a regulator, so don't be surprised to see the voltage get quite high, even as high as 17 volts, so it's imperative you use a marine battery.<br /><br />Chris............
