I have a 32 foot motor
boat on the river. This is realy a sea going boat and has two Volvo Penta
150hp AD31P engines. I go to sea as often as i can but the boat spends most of its life on the river. On the river i only need one engine
running and as it has dp outdrives there is no problem handling it.
There are two 120 A/h batteries charged by each engine
My question is while running the one engine can i put a switch in so all 4 batteries are charged by the one engine.
And if I unintentionally forget to turn this switch off and two engines are running will this damage the alternators
