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.
• Battery volts = Full voltage available at the batteries at the time of the test being performed.
• There are no internally serviceable components in the charger. If the charger has failed then it must be
replaced.
This charger is rated for 115 VAC or 230 VAC operation. When switching
from one input voltage to the other, Wait until all three status LED's
are off. Switching voltage when any of the LED's are on will result in
damage to the charger.
