(5) B -wiring column current test

① turn off the engine, remove the battery and the iron cable terminal, and remove the original lead from the silicon rectifier "engine" (B ﹢) wiring column, and connect the 0-40A current meter to the dismantled lead joint and " Between the "wiring pillar, the voltage table is connected to the" system "terminal, the negative electrode is connected to the engine body.

② Cut off all electrical switches of the car

③ Load the battery and the iron cable connector to start the engine to make the generator work at a slight higher than the rated load speed. At this time, the number of current meters should be less than 10A. The voltage representation value should be within the regulator range specified by the regulator.

④ The main electric equipment connecting the car (such as the high beam, the heater, the air conditioner, the wiper, etc.), so that the number of current representation is greater than 30A. At this time, the voltage representation should be greater than the battery voltage.

⑤ Out of the fire, first remove the battery and the iron cable terminal, remove the voltage meter, current meter, and reinstall the "engine" wire and the battery with the iron terminal of the generator.

If the voltage value exceeds the prescribed voltage limit, it is generally a pressure regulator; if the voltage value is far lower than the lower limit of the voltage, and the current is too small, check whether the individual diode or individual electrode winding should be failed.

(6) The non -disintegration test of the generator

① In order to determine the exact part of the failure and failure of the generator and failure, before the generator decomposes, the generator can be performed unsolved.

② Use the multimeter R × 1 to detect the resistance value between the eternal columns of the generator and analyze and judge.

③ Hand -holding the belt wheel to check the axis shaft and radial gap.

④ Rotate rotor to check the bearing resistance, noise, and whether there are friction and abnormal noise between the rotor and the stator. When the resistance is found, the brush can be removed to determine whether the resistance comes from the brush or the bearings.
