[Clipper17]

Have no spark at idle at cyl nr 2, but somethimes intermittent spark when throttling up. Coils, plugs and sparkplugwires checked out. Need advice about what to check, can I measure DVA-out from cdi-box to coil ? (what value)? All advice will be thankfully recieved. Engine is a 75 hp 3 cyl 2stroke. (1999 mod)

model # would be nice as you are not in the states not sure what would match on this side of the world.

Yamaha service manual will have all the procedures and specs for testing. Your local Yamaha dealer should be able to help get a manual for your motor

This might give some info, but not sure it will be correct for you motor.
There is Yamaha info way on down about page 110.

Powerpack "gone", no dva-output on wire from powerpack to coil on cyl 2. New powerpack connected, engine runs perfect again.
