6.If the power board does not meet the acceptable readings outlined in Table F.2, the board is faulty. Replace. See Power

Board Removal and Replacement Procedure.

NOTE: Complete power board and filter capacitor replacement is recom- mended.

7.If the power board “passes” the resistance test, the IGBT portion of the board is good. However, other circuits on the power board may be faulty. These circuits are NOT readi- ly tested or serviceable.

8.Carefully reconnect leads #201, #204, #205, and #208 to their appropriate terminals. Torque To 75 IN. LBS.
