So I'm on my seventh brand new CDI and fresh out of the package it again doesn't read on my multimeter. Nothing. Not sure if this is a common problem it if I'm just not doing something right but the odds I think would be better than 7 out of 7. The motor Tron registers fine so what am I doing wrong? By the way, they CDIs all came from three different places including bike berry which I figure would be pretty reputable.
