I just bought a used 2007 supposedly BF50 an and I’m having trouble getting the hook up done correctly. This is all new to me so hopefully I can explain the problem where y’all can understand. The harness was removed from the motor when I got it, we jumped straight to the starter in order to do a compression test, around 100 psi on all 3 cylinders. It is missing the lanyard safety switch so I put a jumper in the plug to try and get it to fire on the stand but when I hook up the battery I can’t get any power anywhere on the engine. I think it is probably a simple overlook, but I don’t know where to start. Any suggestions or help would be greatly appreciated.
