Warning! Disconnect power cord before opening the light for repair.
SYMPTOM
PROBABLE CAUSE
CORRECTIVE ACTION
No power
Verify that the AC outlet is functioning.
Power switch not in
correct position
Ensure that the power switch is in ON (|)
position.
Power cord not
plugged in all the
way; or is defective
Check to make sure that the power cord is
plugged in all the way to the device socket. If
the device will still not turn on try another
power cord.
If none of the above restores the light, open the main
enclosure and check for the following:
Damaged power
cable
Check the voltage at the distal end of the
power cable for 12 ± 5% (11.4 V To 12.6 V).
If incorrect voltage is present, remove cable
from the Current PCB and check open circuit
voltage at the ends of the cable. If voltage is
still incorrect, replace the power supply by
attaching a new adjustable arm.
Damaged Current
PCB
Check Voltage at JP1 for the following
values:
Pin 1 +12V
Pin 2
≈
0.6 to 2.4 V
Pin 3 + 12V
Pin 4
≈
0.6 to 2.4 V
If voltages are incorrect replace the Current
PCB.
Voltages depend on the LED forward voltage
and will vary from device to device.
LIGHT DOES NOT
APPEAR WHEN DEVICE
IS TURNED ON
Damaged LED
PCB
Replace LED PCB.
