If the signal level is incorrect the most likely cause of the problem is the
SW2 Transfer Switch itself. However, before replacing an SW2 Transfer
Switch for any failure, refer to the “A21 RF Preselector Input Assembly”
section on page 175 for information on how to verify the control signals to
it.
18.If no problem has been found with the functionality of the SW2 Transfer
Switch carefully reconnect W30, W31, W36, and W37 to the SW2 Transfer
Switch as shown in Figure 4-20. Torque all cable connections to 10 in-lbs.
