Testing the Litebox Charge Connector
1. The Litebox charge connector should be tested to make sure that it is functional.
2. Disassemble the Litebox and remove the battery as shown in Section I.
3. Test the connector and wiring by one of the following methods.
A . If an AC wall transformer is available the output connector from the transformer can be
connected directly to the input connector of the Litebox.
1. Use a multimeter to check the input voltage.
2. Pull the circuit board straight up and out of the slots in the upper housing.
Note :
Make sure that the PC board is on a non-conductive surface whenever power is
applied to it.
3. Place the multimeter into the DC volts position.
a. Place the positive lead onto the soldered connection where the wire is connected to
the
board (this location is marked with a “ + “).
b. Place the negative lead onto the soldered connection marked “ - ”.
c. The meter should read between 13 and 22 volts and a “ - ” should not precede the
reading.
B. If an AC wall transformer is not available the charging connector can be checked by placing
the multimeter into the continuity position.
1. Test the positive input.
a. Hold the input connector so that the keyed slot is facing upwards.
b. Place the red lead from the multimeter into the right socket (located inside the
charging input connector).
c. Place the black lead onto the solder pad marked “+” on the printed circuit board.
d. The meter should beep and indicate continuity.
2. Check the ground input.
a. Place the positive meter lead into the left socket and place the negative meter lead onto
the solder pad marked “ - “ on the printed circuit board.
b. The meter should beep and indicate continuity.
