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 and no less than 80% discharged
as per hydrometer reading.
• The battery voltage must be above approximately 65% of the chargers rated DC voltage. If the batteries
are below approximately 65% of the chargers rated DC voltage, the charger will not turn on.
• If the charger exhibits intermittent problems, it must be in the failed mode for troubleshooting.
• Battery volts = Full voltage available at the batteries at the time of the test being performed.
• This test procedure must be performed in the order it was written. If starting in the middle or skipping
sections when not instructed to do so, the proper results will not occur. If the test result is good, then
proceed to the next test or go to the next section if instructed to do so.
During All Tests
The charger cabinet must remain electrically grounded. Disconnect
both of the battery leads and unplug the charger from the AC source
before disconnecting any electrical component or wire. Failure to do
so may result in serious bodily injury.
