IDK how to bench test a CDI. But...

I always check a CDI against another working new CDI. I bought a few new CDIs a while back.
When I got my new CDIs I tested each one on the bike to make sure they were good.
It's not uncommon to get a defective CDI from China

If I ever have a no spark situation I just try a new CDI
If I still have no spark I know it's not the CDI.

To bench check a cdi you require a multimeter and st it on ohms. I just got a super cdi and being an ex motorcycle mechanic among other trades first thing I do is check electrical components I purchase. Connect meter between red and black wire. No resistance= no good.... BTW mine came with ground wire solder joint to ground pin broken, had to resolder
