So i've got a doozy We have here a 2001 Moto Guzzi V11 Sport (40 000klms) running on one cylinder. It originally melted its right side ignition coil and blew a fuse. Myself and the local mechanic thought we had diagnosed our V11 sport and so we've replaced the ignition coil, we ran the bike on both cylinders for about 5 mins at 1500rpm and FZZZZT (smoke emerges) so now we've melted another, our local mechanic has looked through the bike and believed it is now an earthing issue due to faulty wiring. The Idea was that Voltage was going into the Coil, and not enough was earthing, Thus overheating the Coil. He's contacted us just now and no faulty wiring can be found. The only thing i can think of is that our right side ignition coil is rubber mounted fairly loosely where as the other seems rigid, however i was under the impression that the black cable is the earthing cable and the red is the positive feeding the spark? Before we put the third one in we figured we'd ask the question before wasting more ignition coils here.
