TROUBLESHOOTING & REPAIR

OUTPUT RECTIFIER

REMOVAL AND REPLACEMENT (continued)

9.Using a 3/8 in. wrench, remove the 4 nuts and lock washers holding the rectifier bracket to the machine base.

10.Clear the leads and carefully remove the output rectifier assembly.

11.With a 1/2 in. wrench, loosen the3 nuts holding the rectifier to its bracket.

REPLACEMENT PROCEDURE

NOTE: When installing the output rectifier assembly, apply a thin coating of Dow Corning #340 com- pound to the electrical connections.

1.Fit the new output rectifier into its bracket.

2.Install the output rectifier. Fasten it to the machine base with 4 lock washers and nuts.

3.Install heavy leads X1 and X2 to the terminals at the top of the output rectifier. X1 mounts to the termi- nal nearer to the chopper board assembly. Note placement of fasteners as described above.

4.Install resistor R1.

5.Install heavy lead B5 and resistor lead 2520 to the lower terminal, marked (+).

6.Install heavy lead B1 and resistor lead 2530 to the upper terminal, marked (-).

7.Replace any cable ties removed for disassembly.

8.Install the case side panels.
