9.2 Batteries
Tartan Yachts are factory supplied with batteries. The battery box is located
under the aft berth. The circular, explosion proof main battery switch has four
positions: "OFF”, "ONE", "BOTH” and "TWO".
Note: Do NOT turn the main battery switch to "OFF" while the engine is
running as serious damage to the charging system will result.
Note: The engine manufacturer recommends that you do not change
batteries with this switch while the engine is running.
Recommend batteries are the series G27 deep cycle which is a higher quality
battery (or equivalent).
9.3 Alternator
All engines are equipped with the standard alternator as supplied by the engine
manufacturer. However, you may have an optional HIGH OUTPUT alternator
installed. Please consult the product manufacturers manual for details on
operation and care.
9.4 Charging
System
ENGINE BATTERY (2)
1. The engine battery (2) will only take a charge from the Yanmar alternator if the
battery switch is on (2) or (BOTH) while the engine is running.
2. At the dock the engine battery will take a charge from the inverter/charger only
if the battery switch is set to (BOTH). There is no other alternative to charging
the engine battery (2).
3. Setting the battery switch to (BOTH) is not recommended especially if the
house batteries are drained because the inverter/charger will send the most
charge it can towards the low batteries (house) which will be too much charge
for the engine battery assuming it is fully charged. This will rapidly destroy the
engine battery.
4. The engine battery (2) will not charge at dockside with the battery selector
switch on (2).
HOUSE BATTERIES (1)
1. Underway the house batteries (1) will charge from the Yanmar alternator if the
battery switch is set to either (1) or (BOTH). Again, setting them to (BOTH) is
not recommended.
2. At the dock, the house batteries (1) will charge from the inverter/charger
regardless of where the switch is. Once again, we don’t recommend setting
the switch to (BOTH).
