I am new with Honda motor and would like to know the normal op condition. The Voltage reading is jumping arround from 12.7V to 14.1V with the speed of the boat. I have notice it is at 14.1V @ 2500rpm and drop to 13.2V @ 5000rpm. At 1000 rpm sometime it read only 12.7V. Is this normal for the Honda charging system or should it stay above 13.5V all the time? What am I expecting from it charging system.? thanks
