5.12 Single Engine, Two Batteries and one Dual Battery Switch
The Cape Fisherman dual-battery configuration option uses a Dual Battery Switch. The
switch is mounted with the batteries inside the console. Since most customers order this
option to have a reliable backup starting battery, it is important that the switch be used
properly (position #1) to insure both batteries maintain a suitable charge.
Yamaha Battery Isolator Charging System - Jones Brothers wires the dual-battery
configuration with the optional Yamaha Battery Isolator Charging System. This prevents
draining the cranking battery (#1) by electrical accessories which run off of battery #2. The
isolator system allows for the simultaneous charging of the engine cranking battery and an
accessory battery even when the battery switch is in the default #1 position. Once the
engine is started, the battery with the lowest charge potential will receive the majority of the
charging system output. When the batteries are brought up to the same charge potential,
both batteries receive equal charge output.
STORAGE
When storing your boat, always turn the switch to the OFF position. If an
electrical device was left on, this prevents accidental discharge of the
accessories battery (#2).
STARTING
Under normal operation, select the cranking battery #1 to start the
engine. If the engine fails to start, switch to the accessories battery (#2)
and try again. BOTH or 1+2 should only be tried if the batteries are
discharged to a point where neither alone can provide enough current to
crank the starter motor, but combined in parallel they can turn the engine
over.
RUNNING
With the Battery Isolator system, both batteries will charge with the
switch set to battery #1. If you had to crank the motor using the
accessories battery (#2) or BOTH, try switching back to the cranking
battery (#1) after running the engine for a few minutes.
An explanation of each switch position:
In the OFF position, the two batteries are disconnected from all loads. The OFF position is
used when the boat is being stored or otherwise not in use. It prevents any drain from the
batteries. This can be useful if a circuit has been accidentally left on, say a cabin lighting
circuit or similar drain. Such a load can completely discharge a battery in a day or two,
leading to an unanticipated dead battery situation when you return to your boat.
