Charging voltage on Johnson

[Chris]

I have fitted a Cvolt that allows me to see the voltage across the batteries and it looks like my engine is putting out a charge voltage of around 14.75 volts which is a little on the high side. This voltage is consistent across the RPM range so clearly the regulator is working however what can I do to reduce the voltage a little?

My battery instructions say charging upto 14.8 is OK however I am nervous being so near the the top end all the time.

Try a multimeter - maybe the reading is a little high?

Also depends on how it's wired in - does it measure close to the battery or right at the alternator? You can expect some voltage drop the longer the leads involved.

Keep you eye on the battery electrolyte levels - you will soon see if it's overcharging.

You say the voltage is consistent - it normally varies with RPM - at very low idle you should see less than that.

14.8 is fine-worry if it drops or goes over 15.
