CONVENIENCE PORT

General

This charger is connected to a convenience port which
is located in the dash board of the truck. The
convenience port has an LED status lights that display
in the same manner as the charger. The convenience
port will be connected to the charger via two
connectors. One connector will connect the charger to
the AC Input, while the other connector is for serial
communication and transmission of the LED status
lights.
The convenience port LED status lights display
diagnostic codes according to Table 5. It also flashes
from the center LED to periphery in repeating pattern if
serial communication is lost or if the battery's voltage
is below charger's minimum voltage for charging
threshold. Verify the connection from the 4 pin
connector from convenience port to the 4 socket
connector from charger. If flashing code continues,
disconnect the positive (red) B(+) wire, reconnect, and
try to charge system again. If this does not work, use
an alternate charger to increase battery voltage
reading to 21 volts, sufficient for the charger to
continue charging.
Use schematic below to connect charger. For the
interlock circuit, charger 2-conductor lead CPP 01-B
connects to main harness CRS 01-A. Note: CPP 01-B
has been identify in harness for reference only, but
may not be labeled physically in charger lead.
