[QUOTE="69ST, post: 185736, member: 5"] If you don't have a battery connected, your primary ignition circuit is open. There's jumper lead in the 4-pin battery connector; Honda did this to prevent people from blowing bulbs. The battery is the system voltage regulator; without it, voltages skyrocket. For testing purposes, I'd suggest unplugging the stator from the main wire harness, then running the HT coil input to the primary coil output from the stator. If you get spark, look downstream in the wire harness. If you still don't get spark, time to verify point gap and, possibly, condition of the HT coil. Coils rarely fail. Thus it could be a problem with the condenser; doesn't sound like it, though, based on your reported test result. Start with the easy stuff...we can always go into additional steps, if needed.
