I have a 1991 200hp Yamaha 2 stroke. I have 3 batteries in my boat with an isolating switch. Battery No 1 is single a marine battery. Battery No 2 is two marine batteries connected in parallel. My question is, will the outboard charging system be able to charge all three batteries at once with the switch on "both". What I have been doing is alternating between 1 & 2, but I would like to charge all three at the one time.
 
Re: 200hp charging system

No reason why it can't charge all 3 with it in the " both " position.------------Takes a bit longer, but it will.

^^^^^^^^^

you obvious have no clue

the lower batteries will drain down the other batteries

don not try it or you will be stuck out on the water
 
Re: 200hp charging system

Now I am confused. Is it a NOPE or yes but it will take a little longer. I don't want to get stuck anywhere, which is why I am asking the question. What is 2 x ACR??? Where do I get it and can I install it myself? If the the answer is NO and I don,t have the other thing, I asume it is OK to just charge either 1 or 2 as I am doing now.
 
Re: 200hp charging system

yes

never run on both!!!
also your second bank thats in parallel will not charge fully, so i would run off that after you run to your spot
switch the battery switch over so you know you have a fully charged batt
