Accessory battery going dead??

[2009summit]

Hi All, just bought a 2006 22 VE and the second battery, what I think to be the accessory battery keeps going dead. Thought it was the battery so replaced and now the new one is dead.

I thought this battery would charge the same as the starter battery, is that a correct assumption?

Any advice/comments greatly appreciated.

Other than I love this thing - cheers -

If the boat have the Facoty EIDB dual battery setup, then yes, both batteries get charged when the engine is running. If it's dealer or aftermarket installed, hard to tell how it's setup.

I would start by looking/listening for stuff left on - lights, blower, bilge, ballast pump, stereo, heater, etc. From there, you will need to get an amp meter and do a parasitic draw test.

Cheers, I believe it is the dual set up from factory, will check it out.
