I recently bought a 2007 Nitro 750. I just put 2 hummingbird fish finders on it (798 & 898). I spliced the power into the wires all ready being used by the stock Lowrance that came with the boat. They will only stay on if I keep the key in the run position on the ignition switch. I was just killing the motor with the kill switch, but I think I am doing something wrong. The last time I went out, I got stranded because the cranking battery died. Autozone told me it was a bad battery, but when I tried to take it back to Walmart, they tested it and said it was good and would not let me swap it. The battery is only 3 months old. Is what I'm doing hurting the battery, or do I need to re-wire the fish finders?
