Troubleshooting Guide
c. If the light does not operate with the cell removed, check the wires to the
light and confirm that they are properly connected. Check the voltage from
the light terminals on the power supply board. Set meter to appropriate scale.
You should have about 16 volts DC.
d. Option 1: Check the output of the power supply by using the recommended H.V.
probe and a multimeter. The unit must be "ON" with the operating switch in the
"Max Clean" position and the interlock switch must be depressed. The voltage
should measure from -5.5 KVDC to -7.0 KVDC. An alternate method to check
voltage is by using a plastic handled screwdriver to short the high voltage
contacts and observe a spark.
Option 2: Using a plastic handle screwdriver, short the high voltage contacts
and observe a spark.
If the wire has voltage, the
light is bad and needs to be
replaced. If the wire does
not have voltage, go to
next step.
If the voltage is not present,
check the transformer output.
If the voltage is present and not
within range, replace the power
supply board and check the
transformer output. If the
voltage is present and within
range, the power supply is
operating properly.
Short the HV contacts to
observe a spark.
