Merc 470 voltage
 

My 1982 Searay with a Merc 470 has been getting fluctuations in the volt
meter on the helm. Below 1200 RPM it shows to be slightly discharging. But
when I get higher RPM than that it overcharges. I haven't overhaeted the
engine or anything to ruin the voltage regulator and have had no battery or
other electrical problems since it started. Voltage regulator or something
else? And is there any real problem with it overcharging for short period of
time? I turn everything on electrical I can when this happens.

Are you sure that the volt meter is accurate?

I have to assume so as it does the same thing each time out... discharge at
low spped and overchargeat high sppeds

Try a handheld digital multimeter. Bet your guage is off.

I'll do it this week. In series at the battery or where?

In parallel, anywhere in line with the main power feed, or at the battery.
If it doesn't go much above 14 volts, you aren't overcharging.

I checked and at 2000 RPM I'm at 17.75. How bad is this?

Pretty bad. Your voltage is not being regulated properly, and you're likely
to cook, at least, your batteries, if not also your electronics, engine
electrical, etc. I'd get it fixed before running it.
