I read 2.44V---always---regardless the position in timing, if I measure the voltage with the ignition on and the engine not running. I have also compared my test results to a good, working MSD 8352 which reads +12.54V on my system---always---the 0V pulses being so short in time that you'd need an oscilloscope rather than a DMM.

As I mentioned earlier, the engine starts briefly and then dies. When this happens the coil voltage goes UP to +12.44V, and then the engine dies when the voltage goes down to +2.44V.

Nevertheless, a good, working MSD 8352 would show +12.4V (or so) ignition on, engine running or not, with the pulses so short in time they would not be observable with a DMM.
