TEST EQUIPMENT REQUIRED FOR TROUBLESHOOTING
Digital Multi Meter (DMM), calibrated and accurate down to 0.00001 volts.
Clamp on DC ammeter to measure up to 20-Amps.
Important Notes and Instructions
• This troubleshooting guide assumes a familiarity with the use of a digital multimeter including, voltage
tests, continuity tests and diode testing. If not familiar with any part of these tests, refer testing to a
qualified technician.
• Make sure that the AC electrical socket the charger is plugged into is in good working condition.
• Make sure that the AC voltage at the electrical socket is the same as the AC voltage on the charger
nameplate.
• Make sure the batteries are in good condition.
• If the charger exhibits intermittent problems, it must be in the failed mode for troubleshooting.
• There are no internally serviceable components in the charger. If the charger has failed then it must be
replaced.
DEFINITIONS:
Volts Per Cell = Voltage for each cell in a battery pack. for example, one 6-volt battery has 3-cells.
This charger is rated for 115 VAC or 230
VAC operation (nominal). When switching
from one input voltage to the other, wait
until all LED’s are off. Switching voltage
when any of the LED’s are on will result in
damage to the charger.
GEL batteries must be charged with a
charger configured for GEL batteries. Use
of any other charger will result in damage
to the batteries and premature failure of
the batteries.
