First, you need to replace the internal regulator with an external regulator. It may be that your internal regulator is broken and you can't find a regulator with the right size, voltage, and other settings. switching to an external regulator.
1: First take out the two wires from the excitation carbon brush. Disconnect the power (+) and output (i.e. the two wires connected to the carbon brush) of the original integrated regulator to avoid conflict with the later modified external regulator.
2: Find a suitable external regulator and attach it in a suitable location. (Do not install it near too hot place. It is better to have wind passing through it, with good heat dissipation and relatively durable.)
3: Find out if the modified external regulator is positive or negative. (Whether it is adjusting positive power generation or negative power generation). Of a maGenerally speaking, most external regulators adjust the positive output.
4: Connect one of the two wires of the excitation carbon brush just pulled to the negative (i.e. ground), and the other to the F of the external regulator. If it is a negative regulator, the reverse is true, i.e. one wire is connected to the positive and the other wire is connected to the F of the regulator.
5: The "-" on the regulator is connected to negative electricity, and the "+" is connected to the ignition switch (i.e. the wire that receives the power when the key is on The advantage of this is that when the key is off the engine will not be energized, which will not cause the engine to shut down after stalling. which will not burn the excitation coil and the regulator loses power).
6: Start the engine and check.
