Three Selector Switches with Two Batteries and
Single Engine
Each of the three battery switches have two positions:
All Switches Off
Power supplied to automatic bilge pump, CO detector (if so
equipped), and stereo memory.
STBD Switch ON
Use only STBD (Main Engine) battery.
PORT Switch ON
Use only PORT (House) battery.
STBD, PORT, and PARALLEL Switches ON
Use STBD (Main Engine) and PORT (House) batteries in
combination.
Recommended settings are as follows:
1. All Switches Off
When boat is not in use or power is not required, turn all
switches to OFF. The only power supplied at this setting is
the automatic bilge pumps, carbon monoxide detector (if
equipped), and stereo memory.
2. STBD Switch ON
To start the engine, place switch in ON position. With this
setting, power will now be supplied to your boat from the
STBD (Main Engine) battery. This will allow the engine alter-
nator to charge on the main battery.
3. PORT Switch ON
For cabin or accessory power, place the switch in the ON
position. Power will now be supplied to your boat from the
House battery.
Note: Robalo does not recommend leaving all three switches
on when the engine is off. This will drain both batteries and
you will not have a starting battery.
4. STBD, PORT, and PARALLEL Switches ON
If both batteries are low, you still have the option of starting
the engine by combining the output from both batteries. This
position is also used to charge both the main and house bat-
teries if the boat is not equipped with a battery isolator.
Note: When recharging a low battery, be sure to run the engine
for a sufficient amount of time to fully recharge the battery.
Note: Robalo does not recommend any other settings than
mentioned because of possible damage to batteries or engine
alternator.
