Ok...this topic I'm sure has been beat to death. I've done searches and with such an abundant amount of information I have become more confused than when I started.
I just got a boat and installed a stereo with 2 amps. We parked in the cove and I killed the battery listening to the stereo with the motor off. The boat does have a PERKO switch, however, I don't believe it's wired right. It looks like it's wired in a series (I'll take a pic when I get home) How should I reconnect them? Should I have 1 position for starting the engine, 2 position for the stereo when the motor is off, and put it in the both position when the motor is running to charge both batteries?
Also, I would like to accomplish this without spending more money...at least not now...I've spent so much money on sales tax, registration, stereo, insurance, etc, that I'm sick to my stomach!
