How to distinguish whether a motorcycle magneto coil is a half wave or full wave from the coil itsel

The lighting output lines of the full-wave and half-wave coils are two, of which the two output lines of the lighting coils of the half-wave coil are measured with the resistance of the multimeter, and the two wires are connected to each other, and they are also conductive to the ground and the iron wire; Full-wave coils have only two wires that are open to each other, and neither of them is conductive to ground.

Three-phase generators are full-wave rectifiers, and the wiring is three yellow or white wires; The two wires of the single-phase generator are yellow wires of the same color or other wires are equipped with full-wave rectifiers, and if there are three wires yellow, white and green with half-wave rectifiers.

The coil of the motorcycle magneto cannot accurately distinguish between half wave and full wave from the appearance, so to distinguish the type of coil, you can measure it with a multimeter.

The lighting output lines of the full-wave and closed-wave coils are two, of which the two output lines of the lighting coils of the half-wave coil are measured by the resistance of the multimeter, and the two wires are connected to each other, and they are also conductive to the ground; Full-wave coils have only two wires that are open to each other, and neither of them is conductive to ground.

It's not the same as the wire. That is, the green line, the half-wave is only connected to the iron, and the full-wave is still connected to the coil.

The ignition coil of the half-wave does not have the full-wave one.

Motorcycle half-wave power generation coil and full-wave power generation coil are interchanged, motorcycle half-slope power generation coil is changed to full-wave power generation coil, motorcycle power generation coil line connection and improvement.

Straight to the point ... How to divide DC and AC on it...

Half-wave rectifier circuit.

It is the simplest rectifier circuit. It is composed of power transformer B, rectifier diode D and load resistor RFZ. The transformer converts the mains voltage (mostly 220 volts) into the required alternating voltage E2, and d converts the alternating current into pulsating direct current.

Full-wave rectifier circuit.

It is composed of two half-wave rectifier circuits. A tap needs to be drawn out in the middle of the transformer secondary coil to divide the secondary coil into two symmetrical windings, so as to lead out two voltages E2A and E2B of equal size but opposite polarity, forming E2A, D1, RFZ and E2B, D2, RFZ, two energizing circuits.

The full-wave filter circuit requires the transformer to have a secondary center tap that makes both ends symmetrical, which brings a lot of trouble to the production. In addition, in this circuit, the maximum reverse voltage of each rectifier diode is twice the maximum secondary voltage of the transformer, so a diode that can withstand a higher voltage is required.

If yours is a normal motorcycle, it is divided into two yellow lines (full wave) and single yellow lines (half waves).

The half-wave has a middle tap, and the full-wave does not have [the coil 2 ends are not grounded], and the voltage regulator for the two is also different.

The landlord above said it in detail, but it missed a point, that is, AC and DC

Magnetos are not divided into full and half waves! Only the rectifier is divided, and the waveform can be distinguished from the full wave and the half wave by looking at the waveform with the oscilloscope!
