TM 5-3805-262-34INSPECTION/REPAIR (SHEET 2 OF 5)c.Inspect electrical lead (31) for cracked or broken insulation or broken wirestrands at connection to terminals.d.Inspect springs (28) for cracks, brokencoils, and permanent set. Inspect brushholder (26) and brushes (27) for cracks,distortion, and frayed or broken elec-trical leads. Measure length of eachbrush between shoulder and slip ringend. Brushes should be at least 13/32inch long. Replace brushes (27) withbrush holder (26) as an assembly ifbrushes require replacement.e.Inspect capscrews (4 and 24) for cracks,damaged threads, and broken or defectiveinsulation.

Check capacitorelectrical lead for cracked or broken insulation or broken wire strands atconnection to terminal.g.Inspect voltage regulator (29) for damaged terminals and terminal stud. Testvoltage regulator using commercial regulator tester.h.Test diode trio (5):(1)Set multimeter to X1 or diodecheck range.(2) Hold multimeter red leadat test point A, blacklead at test point B. Notemultimeter indication,then move black lead totest point A, red lead totest point B. Note multi-meter indication. Thereshould be one high multi-meter indication and onelow multimeter indication.(3) Repeat step (2) above at test points A and C.(4) Repeat step (2) above at test points A and D.(5) If both multimeter indications in step (2), (3), or (4) above are thesame, replace diode trio (5).Change 13-211
