Hello all. I recently bought a SeaRay 180 and the first time I took it out on the water, the stereo stopped working almost immediately. I'm a novice when it comes to electrical systems so I've been searching and troubleshooting, but to no avail. The problem: I cannot get my amp to turn on while the boat is running. The facts: -It's got a dual battery system, which I understand usually has a switch and/or circuit breaker in between the two batteries--this one does not, it's just hardwired. -I've tested both batteries, they are both in good working order. The amp is brand new out of the box, I bought it earlier this week. -I've visually inspected all the wiring from deck to amp to battery and back again, it all appears to be in good order. There are two fuses on the large wire that runs from the amp to the battery, which also appear to be in good order. -There is a switch on the dash that activates the stereo deck, it has a two wires that run to the positive side of both batteries, and one wire that is grounded on the port battery. -The most interesting/baffling part: when only the starboard battery is hooked up, the amp turns on every time. The second you hook up the port battery, it goes dead. My conclusion to this was that it must be a problem in the connection between the batteries, but that doesn't appear to be the case. I've tried hooking all connections up to one battery, I've tried switching the batteries, I bought the new amp, I've been fussing with it for three days straight now...what could I be missing? Any help from you scholars would be greatly appreciated.
