9V on your coil is not good.

Is it factory ignition wiring? If so, grab a multimeter and check the wire resistances from the coil to the ignition switch and from the ignition switch back to the fuse box.

Does your fuse box have a plastic cover? Take out your ignition fuse and measure the resistance of the clips that hold it.

I had a bitch of a time trying to find an electrical problem in my 1000 and it turned out to be rusty corroded fuse clips causing it.

Part of the problem was my lack of fusebox cover. The fusebox in the engine bay doesn't help either.
