johnson coil pack testing

[richvan]

I have s 1994 johnson 50 hp that will not start. I believe it to be the coil pack because I put my timming light on the spark plug wires and no spark on bottom cyl
Is there a way the test the coil pack ?

Thanks

Best test is just swap it with one of the good ones.

switch the primary coil leads and see if spark moves to bottom cyl. If it does, pack is bad. if it doesn't, coil assmy is bad.
