Troubleshooting Chart

Isolate from all power sources prior to performing any interior verifications or part replacements.

Symptom

Possible Cause

Action

1

AC Breaker Trips

Incorrect AC Input Voltage

Measure AC voltage and verify against
charger nameplate.

AC Input Taps on Power Transformer
Set Incorrectly

Verify tap settings using charger
schematic or input table found on
charger.

AC-DC Short/AC-Ground Short/DC-
Ground Short

Refer to Section 5.3.1.

High DC Output Voltage

Refer to Symptom 4.

Shorted Power Diodes/Diode Modules
(SD1)

Refer to Section 5.3.3.

High DC Voltage Shutdown Set
Incorrectly

Refer to Section 5.1.2.

Open Gate or Wire on Triac TR-1

Refer to Section 5.3.2.

2

DC Breaker Trips

Shorted Power Diodes/Diode Modules
(SD1)

Refer to Section 5.3.3.

Shorted Battery Cells or Customer
Equipment

Remove all loads and batteries from
A36D and confirm A36D functionality.

Shorted Output Cables

Inspect DC cables for shorts.

Defective Filtering Capacitors

Refer to Section 5.3.4.

Loose Connections on DC Breaker

Inspect DC cable connections and
assure proper insertion.

Incorrect Battery Connected

Measure battery voltage and verify
against charger nameplate.

3

Low Output Voltage or Current

No AC Input Voltage Applied

Measure and confirm input voltage.

Incorrect Battery Connected

Measure battery voltage and verify
against charger nameplate.

Incorrect, Damaged or Loose
Cable/Harness Connections

Visually inspect and verify all internal
wiring using charger schematic.

Incorrect Float/Equalize Voltage
Settings

Refer to Section 3.4.1.1 for output
adjustment instructions.

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.

Defective Power Diodes/Diode
Modules/Triac

Refer to Section 5.3.3.

Defective S2A-341S Control Board

Contact La Marche Service
Department for further
troubleshooting instructions.
