1.Using a 3/8” nutdriver, remove the left side of the case wraparound cover.
2.Locate the output diode bridge rectifier. See Figure F.12.
3.Using a 1/2” nutdriver label and remove the four thick black leads connected to the rectifier.
NOTE: Be sure to label lead terminals also. Take note of washer placement upon removal.
4.Label and remove leads 104A and 104B. See Wiring Diagram.
5.Using a 5/16” nutdriver locate and remove the four bolts mounting the rectifier bracket to the bottom of the machine. These bolts can be accessed easily from the bottom of the machine. See Figure F.13.
6.Carefully manipulate the output diode bridge rectifier and the mounting bracket out of the left side of the machine.
7.Using a 1/2” nutdriver remove the three bolts mounting the bracket to the rectifier. The recti- fier is now ready for repair or replacement. See
Figure F.13.
8.Mount the new rectifier to the mounting bracket using the three 1/2” bolts.
9.Carefully manipulate the rectifier and mounting bracket as a one back into the machine to its proper location.
10.Mount the unit to the bottom of the machine using the four 5/16” mounting bolts previously removed.
11.Reconnect leads 104A and 104B previously removed.
