'69 Dart Custom - Not Sparking

Ok, got it. I moved the new condenser to coil positive along with the other "run" wire. I have the distributor wire connected to coil negative only now.

When the ignition is in "run", I'm getting 12v on both the POS and NEG coil terminals. However, if I connect the coil NEG to chassis, then I get a low-ish voltage on the POS coil terminal (about 7 volts) but no voltage on the coil NEG terminal.

With my new ground cable connecting the NEG coil terminal to chassis, I crank the engine, but no spark and no voltage/test light-up on the negative either (shouldn't that be pulsing?).

Without my new ground cable connecting the NEG coil terminal to chassis, I'm seeing 12v on both coil terminals when in "run" AND crank.

Any ideas?

P.S. According to this YouTube video, the coils terminals should NOT be getting 12v when in "run", but instead some lower amount, because of the ballast resistor - which is why I  tried the makeship coil-to-chassis connection. Is that correct or is something different here? He also speaks about a "badly grounded ignition module" that could cause the coil's voltages to stay at 12v. Does such a thing exist in this car?
