Charging Procedure (Low Maintenance)
If battery voltage is 12.8 V or less, the battery may need
recharging. When using an automatic charger, refer to the
charger manufacturer’s instructions for recharging. When using
a constant current charger, use the following guidelines for
recharging.
NOTE: Always verify battery condition before and
1-2 hours after the end of charging.

Troubleshooting
Starter Motor Does Not Run
• Battery discharged - Low specific gravity
• Loose or faulty battery cables or corroded connections
(see Voltage Drop Tests)
• Related wiring loose, disconnected, or corroded
• Poor ground connections at battery cable, starter motor
or starter solenoid (see Voltage Drop Tests)
• Faulty key switch
• Faulty kill switch
• Faulty Start Diode. Use a digital multi-meter to test
diode operation. Unplug the diode from the harness
under the dash and measure between the Orange and
Orange/Green diode connections. Continuity should
flow one direction only.
• Faulty starter solenoid or starter motor
• Engine problem - seized or binding (can engine be
rotated easily)
Starter Motor Turns Over Slowly
• Battery discharged - low specific gravity
• Excessive circuit resistance - poor connections (see
Voltage Drop Test)
• Engine problem - seized or binding (can engine be
rotated easily)
• Faulty or worn brushes in starter motor
Starter Motor Turns - Engine Does Not Rotate
• Faulty starter drive
• Faulty starter drive gears or starter motor gear
• Faulty flywheel gear or loose flywheel
WARNING
An overheated battery could explode, causing
severe injury or death. Always watch charging
times carefully. Stop charging if the battery
becomes very warm to the touch.
Allow it to cool before resuming charging.
