Ok, let's test under these conditions:

1. stock ignition coils installed
2. stock plug-wires installed
3. stock spark-plugs installed
4. ignition switch ON
5. bike OFF, not running.

6. What's voltage at each coil's RED terminal, using battery negative for ground-probe?
7. While keeping firm contact with test-leads, have assistant wiggle wiring-harness. From battery terminals all way forward to ignition-switch and headlight wiring. Does meter maintain constant voltage? Or does it have drop-outs?
