Check the continuity between slip ring and rotor core

This preview shows page 5 - 6 out of 6 pages.

4) Check the continuity between slip ring and rotorcore or shaft. If there is continuity, replace the rotorbecause the rotor coil is grounded. 5) Check the bearings. If there is any noise, or therotor does not rotate smoothly, replace the bear-ings.SC-00045 (A)Diode lead(B)Heat sink (positive side)

If the resistance is 1 M Ω or more, re- place the stator coil. 2) Inspect the continuity between the stator coil sta- tor core and lead wire terminals. If the resistance is 1 Ω or less, replace the stator coil. 4. BRUSH 1) Measure the length of each brush. Replace the brush if wear exceeds service limits. There is a ser- vice limit mark (A) on each brush. Brush length: Standard (1) 18.5 mm (0.728 in) Limit (2) 5.0 mm (0.197 in) 2) Using a spring pressure indicator, push the brush into the brush holder until its tip protrudes 2 mm (0.08 in). Then measure the pressure of brush spring. If the pressure is 2.648 N (270 g, 9.52 oz) or less, replace the brush spring with a new part. 4.609 — 5.786 N (470 — 590 g, 16.58 — 20.810 oz) pressure is required on the new spring. 5. BALL BEARING Check the ball bearings. Replace the ball bearings if there is resistance in the rotation, or if there is any abnormal noise. 6. OTHER INSPECTIONS Check that the generator does not have deforma- tion, cracks and any other damage. (A) Stator coil (A) SC-00047 SC-00048 SC-02313 (A) (1) (2) SC-00093
