I have zero Suzuki experience but something isn’t making sense to me. You say you have two bullet connectors in the cowl, not connected to anything. Yet in the diagram, the rectifier has three wires that seem to plug into harness 18-19. That would make sense, if, at the end of 18-19, there is a plastic plug, into which should be plugged leads coming from the stator. Then the one wire with the bullet connector coming out of 18-19, hopefully red or yellow, should plug into the fuse assembly, which would then continue to harmess 10, through the key and onto the battery. What doesn’t make any sense is that harness 10 is "harness, starter motor." A 20 amp fuse is too light for that. Also, are your vacant bullets in the cowl coming from the engine harness or the external harness? Do you even HAVE an external harness? Where do those two wires originate? What you have in the picture and what you say you have, seems to either be mismatched or there is more harness on the engine that doesn’t show up in the parts break down. At any rate, I am with Jerry in that if you have a stator wire plugged into 18-19, then that one female bullet coming out of 18-19 should be a low level charge wire….
