Slant 6 No Spark

Montana Y said

I should point out too that the motor turns over and is getting fuel. Also the ballast resistor is new so it's not that either. I did convert the car over to electronic ignition from points when i swapped engines. (old slant 6 was blown, so I put a super slant 6 in). I checked the wiring several times over when i did it, so I know it's correct (I was very paranoid about getting it wrong). And it ran fine for about 6-8 months after the conversion.

Well something hasn't been correct for a month. That's what you need to figure out.
Start with the battery, then check the wiring.
If the problem is (was) strictly the regulator point sticking, then the voltage would follow the rpm. On the ammeter this would have shown as moderate charge at idle, and only pegged charge while driving. That's because (a) the maximum alternator output at idle is usually less than 40 amps. (b) at lower voltage a battery will take less charging current. You've seen that with a light bulb relationship in light bulbs. When voltage drops they draw less current and grow dimmer.
