故障现象:一辆EQ2102型越野汽车,行驶中发现发电机(JFW2621型28V45A)充电电流过小,发动机中、高速时其输出电流只有5～6安,电压只有20伏;而该发电机正常充电电流应为40～45安,电压应为28伏。开大灯时灯光发暗,表明蓄电池亏电比较严重。故障检查:经检查,调节器和发电机的转子、?
Symptom: An EQ2102 off-road vehicle, driving found that the generator (JFW2621 28V45A) charge current is too small, the engine, high-speed output current when it is only 5 to 6 amps, the voltage is only 20 volts; and the generator is normally charged The current should be 40-45 amps and the voltage should be 28 volts. When the headlights light dark, indicating that more serious battery loss. Troubleshooting: After checking, the regulator and generator rotor,?
