9.If the input rectifier does not meet the acceptable readings outlined in Table F.2 the component may be faulty. Replace
Note: Before replacing the input rectifier, check the input power switch and recon- nect switches. Perform the Main Switch Board Test. Also check for leaky or faulty filter capacitors.
10.If the input rectifier is good, be sure to reconnect leads 207, 207A, and 209 to the correct terminals and torque to 31 inch lbs. Apply silicone sealant.
11.If the input rectifier is faulty, see the
Input Rectifier Bridge Removal & Replacement procedure.
12.Replace the case wraparound cover.
