Re: Is the metal body of ignition coil supposed to be grounded? Yamaha G8
That would be the spark plug.
My G9 has a ground wire with a ring terminal that mounts through the bolt on the mounting tabs for it, becuase it mounts into the plastic engine cover. |

Re: Is the metal body of ignition coil supposed to be grounded? Yamaha G8
Ok. That's what I was wondering. The body of my coil was not grounded so I ran a wire with a ring terminal to the battery and the coil started firing. I couldn't see any wire going to the coil. I'll see if I can find a broken wire.

Re: Is the metal body of ignition coil supposed to be grounded? Yamaha G8
Now im really confused. I cannot find any ring terminal or wire that would hook to the ignition coil on my G8.
The wiring diagram for a G9 shows a ground and ring terminal at the coil. The diagram for a G8 does not show this wire. Leading me to believe the coil is not supposed to be grounded. g9.jpg g8.jpg If anyone owns a g8 or g14, would love to know if the body of your coil is grounded. |

Re: Is the metal body of ignition coil supposed to be grounded? Yamaha G8
You are spot on. The g8 diagram shows the spark going through the case, as it should, via a ground. Same thing with the g9. The ground you have circled in the g9 diagram illustrates a system ground and not one that is specific to the coil. The g8 doesnt have that.
