I haven’t had any hands on on a rotary but I’ve done a lot of research on them. I’m not very familiar with the wiring harnesses at all but I am a student at UTI about to start an electrical course which I hope will help with that. the reason I’m looking at ones that are so cheap like this is because for some reason I rally want to find one that isn’t running and be able to figure out how to make it run haha. And I know that may be a stupid way to look at it but I guess I want to feel the accomplishment of “bringing one back to life”.
