22. Reconnect negative battery connections.
23. Verify that the solar panels are charging the batteries by moving the unit into the sunlight and
measuring the current on the solar wire harness using a clamp-on DC Ammeter. The charge controller
may take up to one minute to turn on and requires the battery voltage to be at 12.3 V or lower to start
a charging cycle. Activating the equipment running off the battery will drop the battery voltage to this
level and start the charging cycle.
24. Install the yellow Caution label
(Figure 9)
on the liftgate battery box or near the solar panel terminal
connection. The label must be visible to servicing technicians to warn of additional charging sources.
