I have 2 battery switches..<br /><br />1 is on/off<br /><br />the other is 1/2/both/off<br /><br />I know one is for the port motor the other for the starboard motor.. Do they both run through the 4 way switch??? Does the on.off just run the cabin? and how does they cabin battery get charged?<br /><br />I do not think these were set up right to begin with and now with reomoving and replacing the motors (305 mercruisers) I am REALLY confused..<br /><br />Thanks..
