The car I have has a 12 volt battery. I'm not sure if it was done right. Battery is not charging. I'm trying to figure out if the generator is a 6 or 12 volt. Ther are no markings on it. Took it to an electrical shop and they checked it and said it is working fine. Said he did not know what voltage it is for. He was busy so he probably just said that to get me out of his shop. I looked on line and it stated that if I check the ohms between the field and armature that would tell me. If it is 6 ohms are below it was a 6 volt and if higher it could be a 12 volt. I did that and it was around 16 ohms. Does that sound right.
