Having issues with a Chinese Z50 copy. It runs a 12V system. Now it will not charge the battery. I have a brand new Lifan 70cc motor and new regulator. I have checked that the motor is well grounded to the frame and the regulator should be connected correctly.
I am getting 10-12VAC at idle from the yellow and white cables coming from the stator. At higher revs the output is +50VAC. Is there something else I need to check for to make sure that the stator is functioning correctly?
I have the same VAC coming out at the connector going in to the regulator. The regulator is connected to ground at the frame and also connected to the green wire coming from the stator. However, regulator output is only 5-7VDC. I have tried several regulators and the result is the same with all of them. How can I check that my regulator is not broken?
What else can I check to find the issue? I am running out of ideas. Very thankful if there is someone here who could help.
