6.Using the volt/ohmmeter, check for 10VAC at secondary leads #601 and #602. Typically, these leads are yellow. Place the probes at the lead splices. See Figure F.2.

7.With 115VAC applied to the primary leads #532 and #31, if either or both of the sec- ondary voltages are missing or low the T1 transformer may be faulty. Replace the transformer.

8.After the test is completed, disconnect the 115VAC from the T1 transformer primary leads. Reconnect lead #532 to the power PC board terminal. Close the left side cover assembly and re-assemble the screws.
