LESTER X-SERIES CHARGER
Test Equipment Required for Troubleshooting
•
Digital Multi Meter (DMM)
• Clamp on DC ammeter to measure up to 20-Amps.
•
Small 12 volt battery
•
12 volt test light
• 300 Ohm resistor
• Oscilloscope
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 you are not familiar with any part of these tests, refer testing to a qualified technician.
• Make sure that the AC electrical outlet used is in good working condition.
• Make sure that the AC voltage at the electrical outlet is the same as the AC voltage specified 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.
Theory of Operation
The X-Series charger is a fully automatic microprocessor controlled SCR switching charger.
The charger turns itself on when it is plugged into the AC electrical outlet and turns off when the batteries are fully charged. Once
the charging cycle is complete, the charger will monitor the battery voltage. If the voltage drops below a threshold voltage, the
charger will turn on again for a short cycle to keep the charge fresh.
It is possible that the charger will not turn on if the battery is severely discharged. Should this occur, then the Low Voltage Start
switch can be used to manual start the charger. Refer to the Operation Chapter in the Owner Operator manual for details on
operation of the Low Voltage Start switch.

SLA batteries must be charged with a charger
configured for SLA batteries. Use of any other
charger will result in damage to the batteries and
premature failure of the batteries.
