Also check to make sure everything is switched off. I chased an issue with mine for a month and finally figured out that the auto bilge was sticking. I know the light on the dash lights up, but I just overlooked it. The bilge pump was a new motor and ran so quiet I couldn't hear it. So It kept killing my battery!!!

I suspect it is the bilge motor to drain the batteries that much. I get an indicator light though. Another source drain may be a resistive short to ground like a hot lead connection submersed in water where an uninsulated grounded object is submersed also like at the bilge pump again.

Ok, it was lack of proper battery care that caused the prob. I should have gotten a maintainer last year. One of the batteries had a dead cell when tested under load, the other tested fine. I got a replacement, hooked everything back up, checked for a draw with voltmeter and test light and no draw. Lake tested same day and had a fun, trouble-free day on the water. Learned my lesson for sure, I will be getting a maintainer very soon.

Interestingly, I had a friend who had a snowmobile and a motorcycle battery on a maintainer and lost both batteries when the maintainer failed and became a load rather than a power source.

I had the same issue with my 09 LSV this year. Winterized it last year, disconnected both batteries and placed them both on battery tenders. Hooked everything back of this season, when thru some checks, everything worked fine. Let the boat sit for a week before the weather warmed up, both batteries were dead. Un-hooked everything put charges on both batteries for a day and everything has been fine since. Never could figure out why or how both batteries drained. No switches were left on.
