2 alternator/2battery/75amp Isolator

Ok, I have a question for anyone out there. I contacted Sea Ray the other day because we have had to replace our port battery several times and They told me we should change out the isolator. The one that is on our 1999 Sundancer 370DA is 2 alternator/2battery/75amp Isolator. The only ones we are finding is a 2 alternator/2battery/70amp Isolator and 2 alternator/2battery/130amp Isolator and we do not know which one to buy. I contacted ProMarine and they suggested the 130amp.

Any thoughts on this.:huh:

Get the 130. I think the alternators were somewhere around 65-75 amp output. The 75 amp isolator doesn't have a lot of headroom if the alternators go full output.

Let me ask you this, is- -was the battery charger overcharging your battery?

I know the cells are dry. We do turn off the battery switches when we leave.
