Re: 1997 johnson venum 200 no spark

There is great help on the CDI ignition website. I have not checked for your exact model, but I would go look there. If you have a DVA and a voltmeter, you'll be able to diagnose to the part.
Try these things.
1 Look for a master kill switch shutting you down. It is not likely all six coils have failed at the some time.
2 There is a master kill wire to the power pack that should be unplugged, but, I don't know which one on your unit. If you share model number I might be able to get you close.
3 Look at each cylinder spark output with an air-gap spark tester; looking for spark to jump 3/8"
4 Timer base may not be telling the power pack to fire or telling it to fire at the wrong time. In the case of the latter, you would still have a spark, just not delivered at the right time.
5 Look for good contact on all power pack wires and grounds.
if you have a DVA you can test for a energy coming from the stator, and likewise, energy coming from the power pack to each of the coils. A DVA runs about $30

Look for yellow and black wires and disconnect from the power pack. If spark returns, you have problem withe the kill circuit or ignition switch.

I will stretch and assume you are referring to the voltage rectifier (rec) and yes, it will influence presence of spark. That is a next test. Remove two yellow wires going to the rectifier. Retest for spark.
Just to cover the basics, you will need to spin the flywheel at 250 rpm or greater to have the stator create enough voltage for the coil to amplify. The coil will step the voltage up only so much. The coil won't be able to "pull up" a too low input.
