2004 F25, no spark

[Raif Pomeroy]

Hello sleuths. This is a 2004 F25 with no power at the coil. I replaced the coil, still nothing. I bypassed the emergency kill switch, nothing. The engine develops about 150v at the two wires leading into the coil but nothing out of it. Any ideas at all?

check plugs
spark plug leads
sounds like pulser

no trigger(pulser) inputs and guess what? no coil primary output from the CDI.

however you say your getting 150 Volts at the coil primaries. that indicates the CDI and pulsers are functioning.
what kind of multimeter are you testing with ?
does this setup use the singe coil or twin coil ign?
it was made and desined by Mercury and painted gray for yamaha in the states.
if using the siamese coil either spark plug can take out both.
what kind of spark tester are you using and are you testing both at the same time?
have you done coil primary and secondry resistance tests ?
