With my scooter (btm bt49qt-20a) the fuse, which hangs on the thin red cable from the battery, burned immediately when the ignition was switched on. As a result, the electronics were completely gone (light, horn, indicators), but the scooter got started and the engine was running. Now I removed this part, because it obviously burned through somehow, and everything works again as it should. I did not bridge the place where it was. Who has an Ahun g what that could be. I assume it’s some kind of resistance (measuring device indicates 6.4 ohms) but for what, even if everything works without it?
