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

Red and black reading 4.0
Blue and black reading 22.0
No spark when installed on bike.
