I replaced the generator with a new one, why is the light still on?

I don't know what type of generator this car uses (with or without a regulator). If it is its own generator, the light may be on due to aging of the wiring (from ignition switch to ignition switch). Indicator light). There is a small voltage difference on both sides of the indicator light. Of course, the brightness is very low. If it has an external regulator, check whether the generator's n-point line is energized and whether the section from it to the regulator is open circuit. If there are no problems with either, replace the regulator. .
