Battery specs?

[Dom08]

Hey Guys,
I have finally gotten the chance to work on the 03 moomba outback
I am working on the electrical system and i was looking to change the batteries to AGM since i had some battery electrical issues that burnt the terminals last season.

I looked in the manual for battery specs and it says cold crank amp is 650. The batteries that are in the boat now are 1000amp crank.... also the specs says its 12v neg ground.... and i have the battery isolator relay has a stamp of 24v on it...


Can these cause problems that i may be seeing?

No issue going with a higher CCA, its actually a good thing.

Link to the battery isolator?

Theres no label on it but it looks just like this

All it says on it is 24v

1000 CCA is pretty standard for marine starting batteries. What is the relay located and what is wired to it.

[Dom08]

The relay is mounted just above the batteries on the wall. The positive terminals hook up to the relay.

There is a black wire which hooks up to 1 negative terminal on one battery. There is a red wore from the relay thatgoes to the driver area (ignition?)

Looks like its just a heavy duty continuous duty solenoid. If it opens and closes, I would not worry about the 24V stamping on it.
