Ok, the time has come to educate the Tige community on the two typical battery switches commonly found on boats.
The switch on the right is a traditional dual-bank 4 position switch. It offers OFF, bank-1, bank-2 and a combined 1+2. This switch allows charging both banks while engine is running, isolating one bank while at anchor, to restart the engine after. You can alternator between banks. You will NOT find this switch as the OEM on a Tige from about 2010 to present.
The switch on the left is the Dual Circuit Plus switch. Its a dual pole dual throw 3 position switch. It offers OFF, ON and COMBINE. There is NO battery-1 or battery-2 positions. Both banks are turned ON or OFF or the banks are combined. Paired with a voltage sensing relay or diode isolator, operation is very simple. When you get in the boat, turn switch to ON. When you leave the boat, turn the switch to OFF. If the cranking banks seems weak, move the switch to the COMBINE position at about the 4 oclock position to get help from the house bank. With the mentions relay or isolator, the alternator WILL charge into both banks while the engine is running.
As you can see, these two switch types do not operate the same. so its very important to know which switch type you have, in order to understand how it functions.
