1.闭合电压的调整用一节干电池(1.5伏)与蓄电池(12伏)、电流表串联,接在调节器的蓄电池接线柱上。逐渐升高发电机转速,在截流器触点闭合时,观察车上电流表的指针。若电流表指针向“+”方向摆动,表示闭合电压高,应该减弱弹簧拉力;若电流表指针
1. Closing voltage adjustment with a dry cell (1.5 volts) and battery (12 volts), ammeter in series, connected to the regulator battery terminal. Gradually increase the generator speed, observe the car’s ammeter pointer when the interceptor contacts are closed. If the ammeter pointer to the “+” direction of swing, said the high closing voltage, spring tension should be reduced; if the ammeter pointer
