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. 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. 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. 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. Option 2: Using a plastic handle screwdriver, short the high voltage contacts and observe a spark. Short the HV contacts to observe a spark. 8
