6. Measure voltage at power distribution board PCB6 (Figure 3-1, item 1). Look on the board for fuses F1 through
F4 (Figure 3-2). 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 1 or more of these points, disconnect power and troubleshoot PCB6
fuses and associated pins, connectors and wiring between power distribution board connector REC1 and
transformer secondary T1 (Figure 3-1, item 6).
Also, check main power fuses F1 and F2 (Figure 3-1, item 3) and associated wiring and connections between
T1 and L1 and L2.
Repair or replace any defective components.
