6. Measure voltage at Power Distribution Board PCB1. Refer to Figure 8-2 for detail of PCB1. Look on the
board for fuses F1- F4. Measurements between each fuse and chassis ground should be as follows:
F1: 24VAC
F2: 120VAC
F3: 240VAC
F4: 120VAC
If voltages are not present, or incorrect at one or more of these points, disconnect power and troubleshoot
PCB1 fuses and associated pins, connectors and wiring between power distribution board connector REC1
and transformer secondary T1. Refer to Figure 9-4 for location of T1.
Also, check main power circuit breaker CB1 located in Figure 9-4, and associated wiring and connections
between T1 and points L1 and L2 (including linkboard).
Repair and/or replace defective component(s) if necessary.
