Charging voltage on Yam 90?
When battery is not 100% full or when using running lights, charging voltage is roundabout 14.5 V, But when battery is 100% full and I am not not using any electricity, voltage goes up to max 15,4 V ,but never more.
Swapped to a fresh battery(65 or 70 amp, don't remember), same result, when full, voltage is a tad high. Behavior is very consistent, no unexpected fluctuation occurs. But as mentioned any significant use of power and it drops normal level. Is the regulator going or is it just normal as "no way to go" for the electricity when battery is full?
fun on a boat is inversely proportional to size...sort of anyway
