sories draw power from the batteries.
Battery Isolator System
The models with a single engine and two batteries are standard with
a battery isolator system to maintain a charge on the house battery
while the engine is in operation. Models with twin engines and three
batteries are standard with a battery isolator system to maintain a
charge on the house battery while the starboard engine is in opera-
tions. The isolator for Yamaha powered boats is in the engine and
for Honda powered boats, it is in the aft bilge.
Battery Selector Switch
All models have a battery selector switch as standard equipment. If
your boat has a battery selector switch, you will find it in the aft rig-
ging area or in the console.
Single Selector Switch with Two Batteries
A selector switch with two batteries is standard on some models.
This battery selector switch has four positions:
OFF Power supplied to automatic bilge pump, CO detector (if so
equipped), and stereo memory.
1. Use only Number 1 battery
ALL Use Number 1 and Number 2 batteries
2. Use only Number 2 battery
Recommended settings are as follows:
1. When boat is not in use or power is not required,
turn the switch to OFF. The only power supplied at
this setting is the automatic bilge pumps, carbon
monoxide detector (if equipped), stereo memory,
and optional corrosion protection system.
2. To start the engine, place switch in Number 1
position. With this setting, power will now be sup-
plied to your boat from the Number 1 battery. This
will allow the engine alternator to charge both
batteries.
3. For cabin power with engine off, place the switch
in the Number 2 position. Power will now be sup-
plied to your boat from the Number 2 battery.
Note: Robalo does not recommend leaving the switch in the
ALL position when the engine is off. This will drain both
batteries and you will not have a starting battery.
4. If one battery is low, you still have the option of
starting the engine from the other battery.
Example 1: If the Number 1 battery is low, place the
switch in the Number 2 position. Then start the
engine. Place switch in Number 1 position. This will
allow the engine alternator to recharge both batteries.
Example 2: If the Number 2 battery is low, place the
switch in the Number 1 position. Then start the
engine. This will allow the engine alternator to
recharge both batteries.
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.
