FIGURE 4-4. TESTING BRUSH ASSEMBLY
Check or replace exciting diodes as follows:
Set multimeter for ohms and check exciting diodes (refer to Figure 4-5) by noting
multimeter indications between each of the diode leads (A) and the D+ stud (B). Reverse
multimeter leads, repeat checks and note indications.
If readings are the same in both directions for any diode, replace exciting diodes
assembly. A good diode will show a high indication in one direction and a low indication
in the other.
