• Remove the battery from the battery
compartment
Testing the battery:

set to Voltage
• A fully charged battery should read 13.0-13.5V. An

• If the battery is showing under charge condition,
charge the battery using a trickle charger at 7
amps for 10 hours. When charging the battery, it
should be removed from the unit. Connect the
