Here is a question regarding the Perko battery isolator switch on my '92 Bayliner 2655: Does the alternator charge both batteries in the ALL position?
It is my understanding that you should only start the engine with the switch in the ALL position since the batteries do not charge in the ALL position. After the engine is started, the switch should be set at the 1 or 2 position, where the battery that the switch is pointing to will charge using the alternator. Is this correct?
The boat manual says that only the on board shore-powered battery charger will charge BOTH batteries simultaneously, when the Perko switch is set at either 1 or 2 (not ALL).
My setup is 1=Starting battery (1000 cold cranking amps) and 2=Deep Cycle (550 cold cranking amps).
Thanks in advance.
