Find a schematic diagram for the bike and figure it out with an ohmmeter, which you must use when the battery is disconnected. Find the electrical resistance in ohms of every coil in the bike. I rather doubt that you'd have damaged the electronic ignition module, but I suspect that others here will be able to help you test it. Just test one part of the ignition--including less obvious stuff like switches and wire connectors--and eventually you will discover the problem. You'll also learn the fine art of electrical testing.
For quick and perhaps more definitive tests of switches and connectors make yourself a continuity tester consisting of a battery (your bike battery will do) and a bulb, and a pair of wires connected so that the bulb lights when the wires are in contact with each other. This will test switches, wires, wire connectors, and to an extent the sturdier coils in the bike.
