With no load on it, at a fast idle, my 35 amp Motorola alternator takes over 25 minutes to raise the voltage of my starter battery from its resting charge of 12.6V to 13.5V As soon as I lower the engine revs to a slow idle the voltage begins to drop 0.01V per minute. If I stay at fast idle and turn on the Bilge Blower the battery voltage drops more than 0.6V at about 0.05V per minute.
Is this happening because the voltage regulator is not working? Why does voltage keep dropping under load when I'm running the engine more than 1200rpm under load or with no load? Am I draining the battery by running with the bilge pump on? Can I run the Atomic 4 without the bilge pump on after I use it to clear any fumes before starting the engine?
The bilge blower seems to draw a lot of amperage. What would an average amp draw for a blower in a 4" diameter hose be?
I keep the starter battery charging on a 21W solar panel all the time just in case I'm draining it by running with the bilge pump on.
Thanks for any help with this.
