Juice, but no click.

By the way, I highly recommend the relay work-around. (That is if you're just getting low voltage at the coils, not zero.) If you have low voltage at the coils and just can't seem to clean it up, a relay with a direct feed from the battery works great.

I had 0V here. My '75 KZ400, though, is on her 3rd coil. (Initial one was bad, a brand new AC Delco (for a car) was bad out of the box (???), and the one that's in there now is from a CB350). To complicate things, the coil ground was bad (through a wire and wiring harness, no less), and now, I find that the starter switch is bad. May have to use the "secret starter button" hidden underneath the seat or something...... Good thing she has a kick start.

My friend has the "secret starter button" on his Honda courtesy of a PO. Pain in the butt. ;-) Actually his is a pain because his regular switch works some of the time and the "backup switch" is under the sidecover. That would bug the heck out of me, but it's his bike... ;-)

Yes! You need to have a good multimeter. Most multimeters have an audible "continuity" feature which obviates the need for a separate "test light", so just get a multimeter. I prefer the audible continuity tester over the visual light anyway (don't have to crane your neck to see it whilst holding the tester leads in sometimes awkward positions).

I've been wrenching bikes for almost 25 years. A test light, while less "techno" will tell you the same exact info as a multimeter when it comes to BASIC chassis electrical. A multimeter in the hands of a new backyard mechanic will yield far more confusion than good. Multimeters certainly have their need for advanced diagnostic tasks, but for the novice a test light is the best answer.

I guess you have a point there. As an IT pro who's also been messing with electronics since I was a kid, I feel pretty at home with a multimeter but I know not everyone is.
