Charging Procedure
If battery voltage is 12.6 Vdc or less, the battery may need
recharging. When using an automatic charger, refer to the
charger manufacturer’s instructions for recharging.
Do not exceed 9 amps when charging the battery.
NOTE: Charge the battery using an automatic
charger that will not exceed 14.6 Vdc. An automatic
charger will signal when charging is complete.
NOTE: Allow the battery to stand disconnected for
at least 1-2 hours after being properly charged. If the
voltage drops below 12.6 volts, charging was
ineffective or the battery needs to be replaced.
NOTE: Follow the charger instructions supplied by
the manufacture regarding the order or connections,
switch positions and when to connect the charger to
an outlet.

Troubleshooting
Starter Motor Does Not Run
• Battery discharged
• 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 starter solenoid or starter motor
• Engine problem - seized or binding (can engine be
rotated easily)
Starter Motor Turns Over Slowly
• Battery discharged
• 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
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.
