Bank #1 says it's for "trolling battery #1". Bank #2 says it's for the "starter battery". Bank #3 says it's for "trolling battery #2"". Right now, I am troubleshooting bank #1 because it doesn't seem to be working, but the other two banks seem okay. If, indeed, bank #1 is shot, I am wondering if I can hook up my #1 trolling battery to Bank #2, even though bank #2 states that is is for the "starter battery". Will this cause any problems? I don't see a need for the starter battery to be hooked up to the charger at all since it gets recharged when I run the motor.
