First remove the \"magnetic field\" connection, then use a screwdriver to connect the generator \"+\" and \"F\" terminals. If charging, the generator itself is good, the fault is in the regulator, the general situation is more low speed contact oxidation, ablation or low voltage value; if still not charging, the fault is in the generator.

At any instant, only one positive diode and one negative diode are on, and the positive and negative diodes will not be two in the same bridge; the neutral terminal N of the generator, whose neutral voltage is twice the output voltage of the generator; when three positive diodes are connected together at the negative end.
