I have a 2575 QCW IO. I have battery 1, battery 2, or battery 1&2 as options. I have a plug in the back to trickle charge. I ran into a problem recently where my radio wouldn't work (the amp light was off) and the engine shutoff when I was cruising across the lake and hit the trim button. I was set to battery 2 and hadn't trickle charged ever. Someone told me I should be set to 1&2 because 1 cranks the engine and 2 runs my electronics, and the alternator charges 1 first. Is that accurate?
