Coil trouble

[StephenFZS600]

Hi, I'm having a bit of trouble with getting a spark to the engine. I've tested everything and the voltage stops at the coils, what resistance should I be looking for on the coil packs? Thanks

Resistances are in the Yamaha manual in the downloads section. Have you got 12v on both red/black wires to the coils? Are you grounding the plug/lead to the cam cover? - it is insulated from the engine by the gasket and the seals on the bolts.
