* Check that there is continuity between each stator lead.* If there is no continuity, the lead has broken.(2) Continuity between each lead wires and the core * Check that there is no continuity between lead wires and the core.* If there is continuity, the lead wire has short-circuited. Inspection: Brush* If the length of the brush has reached wear limit, replace the brush. Inspection: Rectifier* Check the function of diodes within rectifier properly. If any fault is found, replace the rectifier. If resistance is infinite in both cases, the diode is open.If resistance is close to 0 ohms in both cases, the diode is shorted.A, B, C: Lead connecting area of stator coilD, F: Heat sink areaE: Regulator connecting area* Inspection should be conducted twice, changed over the positive probe and the negative probe of the tester.* When inspecting using a tester, the current flowing through the rectifier is smaller than usual. Therefore, an incorrect resistance value may be indicated on the tester. Additionally, incorrect indications become larger as the range of the tester gets smaller. Set the tester to the largest possible scale. Assembly Procedure Assembly: Regulator and brush holder* To install the regulator and brush holder, follow the disassembly sequence in reverse. (See " Disassembly: Regulator and brush holder".) Assembly: Brush * Install brush on regulator and brush holder in the direction as illustrated.* After installation, solder the lead wire of brush on the regulator and brush holder. Thereafter, fit the cover as it was. Assembly: Stator* To install the stator, follow the disassembly sequence in reverse. (See " Disassembly: Stator".) Assembly: Rotor and rear bracket * If brush protrudes from regulator and brush holder, rotor cannot be installed onto the rear bracket. In this case, do the following:* Push brush into regulator and brush holder.* Insert pin into rear bracket from the rear to hold brush.* After assembly, remove pin gently.#950 Inspection Of Alternator
Performance Test* The general inspection is only a simplified check. use a test bench for accurate checking.* Connect the meters to the alternator as shown.
* To prevent possible injury, be sure to disconnect the negative terminal of
