Low Output Voltage
or Current (Continued)
Low Output Voltage Condition:
Charger is in Current Limit
Measure output current and verify against
charger nameplate. If found to be in
current limit, wait for batteries to charge or
remove loads.
Low Output Current Condition:
Batteries are Fully Charged Confirm by changing to Equalize mode;
current should increase.
Meter Reading Incorrect Voltage or Current Refer to Symptom 4.
Defective Control Panel
Disconnect the blue and black wires going
to terminal #1 on control panel. Connect
the two wires together, but do not
reconnect to panel. Connect battery and
turn on charger. If the output rises above
the nominal voltage, the control panel may
be defective.
Defective Control Relay
Measure the DC voltage from terminal #1
on the control panel to the positive output
terminal of the battery charger. If no
voltage is measured, the relay may be
defective.
Open RC Resistors
Measure resistance of component. If open,
the resistor may be defective.
Defective Diode Heat Sink Assembly Refer to Appendix E.
Defective Batteries Check battery cells.
6
High Output Voltage
or Current
Incorrect, Damaged or Loose Cable/Harness
Connections
Visually inspect and verify all internal
wiring using charger schematic.
Incorrect Battery Connected
Measure battery voltage and verify against
charger nameplate.
Incorrect Float/Equalize Voltage Settings
Refer to Section 5 for output adjustment
instructions.
Open RV1 or RV2 Resistors or Slider Bands
Measure continuity of resistors. If open,
the resistor may be defective.
Measure resistance from one end of
resistor to each slider band. If open,
readjust slider band.
Defective Control Panel
Disconnect and separate blue and black
wires going to terminal #1 on control
panel. If the charger shuts down, the
control panel may be defective.
Defective Batteries Check battery cells.

Ground Detection Fault
Ground Fault Present on Charger or DC System
Isolate charger from DC system by
removing all wires from charger output
terminal. If ground fault on charger clears,
problem may be on external DC loads,
battery, or wires. If ground fault is still
present on charger, contact La Marche
Service Department for further
troubleshooting.
5.4 Ordering Replacement Parts
Contact La Marche to place an order for spare or replacement parts. To order replacement parts; please provide
the model and serial number of the battery charger, the part needed, and the quantity required.
