How To Check The Voltage Regulator And Magneto Of A Three-wheeled Motorcycle

Check whether the magneto is generating power, rotate the multimeter's rotating disc to the voltage AC range, and then use the red pen probe to connect the yellow wire, and the black pen tip to the pink or other yellow wires to see if there is voltage. It means that the magneto is good. Investigate the voltage regulator, turn the multimeter's rotating disc to 20V, and then use a red pen probe to connect the bottom line of the voltage regulator, and then look at the voltage displayed by the multimeter. If it is higher than 12V, it means the voltage regulator. Yes, lower than 11v is proof that there is a problem with the regulator.
