Default 46 v8 dist wiring

i have a 46 Ford that i can't get any spark to plugs. With neither wire to coil, and I touch dist wire to coil terminal I get a spark at terminal. why is this happening and is it correct? No other wires on coil or dist are installed.

Welcome to the Barn. The information on page two in particular, may be helpful, and I'm sure other members will add suggestions.

That is not correct; so good question. With neither wire connected to the coil, where is the voltage coming from to create a spark? Certainly not from the distributor unless there was a charge on the capacitor. Did it spark just once, or the sparking would repeat? Are you still 6 volts positive ground? Was the ignition switch on or off when you did that?

Coils can store energy. Putting the distributor wire back to its position on the coil can ground the coil causing a discharge seen as a spark. With the distributor points closed the wire will have a ground path. Sounds correct to me.

Coils can store energy? I didn't know that. I'm skeptical.

Maybe if it had a real good condenser installed.

My mistake. Condenser stores energy, not the coil.

Not your mistake, drolston. Someone else said "coils can store energy". You suggested discharge from the capacitor (AKA condenser), which does seem like a possibility to me.
