6.If the input rectifier does not meet the accept- able readings outlined in Table F.1, the com- ponent may be faulty. Replace.

NOTE: Before replacing the input rectifier (D1) check the input power switch (S1) and perform the Primary Power Board Resistance Test. Also check for leaky or faulty filter capacitors.

7.If the input rectifier is good, be sure to recon- nect leads #207, #207A and #209 to the cor- rect terminals and torque to 31 in.-lbs. Apply a coating of Essex D-4-8 insulating com- pound and Dow Corning 738 Silicone Sealant.

8.If the input rectifier is faulty, see the Input

Rectifier Bridge Removal & Replacement procedure. See the Wiring Diagram and
