I’m almost finished with my 1977 KZ650 Digger chopper project. The wiring had been butchered by a previous owner. I rewired it pretty much from scratch and it starts and runs great. However it’s not charging. Is there a way to test stator output with the engine running. I’d like to make sure it has sufficient output before looking at the rectifier and regulator. I’m sure this topic has been addressed previously but I didn’t find what I was looking for with the search function. Thanks for any assistance.
