Electrical System
the ON position to isolate the circuits for normal
operation.
The engine charging system charges the engine
battery and the accessory battery through an
ACR (Automatic Charging Relay) battery isolator
system. The ACR manages the charging current
for the 12-volt system whenever the engine is run-
ning. It automatically combines batteries during
charging and isolates batteries when discharging.
The Start Isolation feature protects electronics
from voltage sags and spikes by automatically
isolating the engine and accessory batteries during
engine cranking. A status LED indicates the cur-
rent mode of the ACR. The modes are as follows:
• LED Solid On - Batteries combined & charging
• Single Flash - Batteries isolated & on standby
• Double Flash - Batteries isolated during engine
cranking
• Triple Flash - Batteries isolated due to low
voltage in one or both batteries
When the engine is running, the ACR circuit senses
the charge and monitors the engine battery volt-
age. When the battery voltage increases to the
“Combine” level, the ACR connects the charging
circuit to both batteries and the charge is split
between the batteries. When the engine is turned
off, the charging stops and the sensing circuit
turns off the ACR, disconnecting the batteries
from the charging circuit, thereby automatically
isolating the batteries from one another.
While in port, while trolling, or at anchor, the
accessory battery will provide current to the boat
accessories and electronics. This will keep the
engine battery in reserve for starting the engine.
The battery switch should be turned to the “OFF”
position when leaving the boat unattended.
Notice:
Current is supplied to the automatic float
switch and manual switch for the bilge pump
when the batteries are connected, even if the
battery switch is off.
