SECTION VII
TESTING/REPAIRING THE CHARGING SYSTEM
The Litebox charging rack is available in two configurations. Both systems have a two pin
connector located at the rear of the charge rack which provides charging power to the Litebox.
The difference between the two systems is the way which external power is delivered to the
charge rack. The Litebox Vehicle Mount System has a 12VDC power cord which is permanently
attached to the charge rack. The Litebox Standard System rack has a power input connector
which is mounted on the side of the rack housing. Systems which use a charge rack must be
tested with the Litebox removed from the rack.
Testing For Input Power From The AC Wall Charger
1. The AC wall charger can be tested by simply measuring its output
voltage.
2. Make sure that the wall charger is plugged into a functioning 120Volt
AC outlet.
3. Place a multimeter in the DC volts position.
4. With the charge connector facing towards you the black key should
be located at the top of the connector (see illustration).
a. Place the positive lead from the meter onto the left pin of the
connector.
b. Place the negative meter lead on the right pin.
5. The meter should give a reading between 13 and 22 volts and
there should be no indication of reversed polarity.
6. If the voltage or polarity is wrong replace the charger.
7. Do not attempt to repair the AC charger.
Testing For DC Input Power
DC - 1 System (cigarette plug)
1. Connect the DC-1 charger plug to its power source (power point, cigarette lighter outlet, etc.).
2. Place a multimeter into the DC Volts position.
3. The voltage should be measured as directed in step 4 above (AC testing).
4. The meter reading should reflect the vehicle’s supply voltage and should be between 12 and
15 Volts DC.
A . If there is no reading the system needs to be checked.
1. Place the multimeter into the continuity test position and place the positive lead onto the
left charge connector pin (with the connector facing you, key on top).
2. Place the negative meter lead onto the tip of the cigarette lighter plug.
3. The meter should beep and/or indicate that the circuit is complete.
a. If the circuit is not complete then the fuse may have blown or the wire may be broken.
b. Replace the fuse by unscrewing the end of the cigarette lighter plug.
c. Replace the fuse with a 20mm X 5 mm fuse (2 amp slow-blow, 2 amp fast-blow, or
5 amp fast blow).
B. Test again as in steps 2,3,4 above.
1. If the circuit is still not complete disassemble the cigarette lighter plug and inspect the
connections.
2. Repair any loose or broken connections.
