I just purchased a used bike with a Merlin alarm system installed. The dealer said it was simply disconnected to save battery. Just got back from my spring service and asked the tech to reconnect the alarm. When he removed the fairing, all the black wire leads (one of them live; still connected to the battery) were cut. Does anyone know anything about the Merlin systems? Is it trash now that the black leads have been cut with no obvious way to distinguish which black wire is for what? Are these alarm systems even worth having?
