4. Locate label and remove leads 19C

and 19D from the reconnect switches
with the 3/8 in. wrench. Note lead
placement for reassembly. Clear leads.
Refer to Figure F.2.

5. Using the Analog ohmmeter, perform

the resistance tests detailed in Table
F.1. Refer to Figure F.3 for the test
points.

TEST PROCEDURE

1. Remove input power to the Power

Wave 455.

2. Using the 3/8 in. nutdriver, remove the

case top and sides.

3. Perform the

Capacitor Discharge

Procedure.
