1987 CDI

So my CDI died, All of my numbers check out good on the charging stator and trigger, so I found a used CDI on ebay. I put it on and it is getting a spark but its putting out a spark on every stroke, not just the power stroke, basically a constant spark as the engine turns over. As you can imagine this doesnt work. Any possiblity the trigger is causing this? It checks good on resistance, I cant imagine how it could constantly send a signal. seems like this CDI is bad too, it is a used 87 CDI. anybody?

TW's use a`wasted spark system. It fires every revolution.
Every rev, rain or shine, intake or exhaust stroke. Spark isn't your problem.
