Assembly.)

To reinstall the High Voltage Capacitor Assembly, reverse the steps.

WARNING! This unit may contain lethal voltages. You MUST completely discharge the high voltage

capacitor before removing from unit. DO NOT SHORT THE TERMINAL ENDS OF THE
CAPACITOR.

Step 1: Open the High Voltage Capacitor plastic
isolator by lifting the

Mylar

tape

.

Step 2: Bleed the excess voltage using a resistor
with values of approximately 5 kohms, 25 watts
for 10-20 seconds. Measure the voltage on the
capacitor terminals.

Step 3: When the capacitor voltage is at 0 VDC,
disconnect the inductor wires and capacitor
terminal wires.
