To or from the coil? You might see a blip of voltage coming from the CDI to the coil, but unless you have a good quality meter, you might miss it. If you have a min/max setting, that is the time to use it. I agree the coil may be bad, I have heard some being bad out of the box. The coil is pretty easy to read, resistance across the two leads, then resistance between the leads and the plug wire. They should show similar resistances. The CDI, however, is much harder to diagnose, almost to the point of using a known good part in place of it.
