The alarm unit is just for oil temperature - it has nothing to do with spark - when you turn the key on, the light should light for a few seconds and then go out - if it does this, the unit is working properly
If you can wiggle the wires on the CDI unit and get it working again, it's probably just corrosion in the connectors - unplug them, spray them with electrical terminal cleaner, coat them with dielectric grease and plug them back together, also loosen and re-tighten the frame ground connection at the ignition coil and battery - if this solves the problem, you are done - if this does not solve the problem, it might be a bad pulse generator (ignition signal coil) or any of many wiring connections including the battery, fuse, coil connections, intermittent ignition switch or handlebar kill switch.
Hope this helps
