TROUBLESHOOTING CHART
Unit will not charge
(Low battery) 1. Charger defective
2. DC jack defective
3. Cable loose or
defective
4. Battery defective
5. V100 too far from
lights
5. Make sure the unit is within 25 inches of th e headlights, if a “Dim Lamp” signal
appears. If the problem cannot be resolved, call 1-877-343-7703 .

1. Plug charger into 120 volt outlet and using a DC voltmeter , check the output
voltage of the charger. Voltage readings can range between12 and 18 D C volts.
If the readings are acceptable, proceed to N umber 2. If the readings are not in
range, call the 1-877-343-7703 .
2. Using the 4 screws on the back of the V100, remove the back cover plate.
Disconnect the battery cable connector so the battery is not powering the unit.
Now plug the charger into the V100 DC jack and try to turn on the unit. If the
V100 will not power up with only the charger , call 1-877-343-7703 . If the
unit works with the charger proceed, to Number 3.
3. While the unit is still plugged into the charger and with the battery disconnected,
take a voltage reading on the battery connector cable coming from the main PCB
board. The voltage reading should be within 2 or 3 volts of the charger reading
taken in Step 1. If a reading cannot be obtained, call 1-877-343-7703 . If a
voltage reading occurs, proceed to Number 4.
4. Remove the battery pack from the unit and check for loose wires. Using a
voltmeter, check the output voltage of the battery. It may be necessary to move
the wires on the battery’s connector while reading the voltage to check for shorts.
Note: The unit will not power up on the battery alone, if the voltage drops
below five volts.
If the battery appears to be defective, call 1-877-343-7703 . If the
battery checks OK, let the unit charge overnight. If unit still fails to charge, call
1-877-343-7703 .
