11.9 is already way low on the high side of the ballast. The less voltage there the weaker the spark will be at the coil. Agood healthy battery voltage should be around 12.4 to 12.6 engine off. So if your battery at rest has that you need tto run through all the connections to the ballast resistor point and make sure they are clean and secure. good clean grounds are also very important. should be almost no voltage drop on all the + wires everywhere. Cleaning all of your bulkhead connector pins and die electric greasing them is also crucial.

I can't be much more specific with the ignition itself withoutseeing what kind and the wiring itself. Perhaps someone more knowledgeable on mopar e.i. than me might know. I'm only super familiar with my own home made t.f.i system.

edit. Is it points now then? And used to be e.i.? If that's the case. Clean clean clean. I would do a new condenser and a ballast resistor just to be sure. But like I said. 11.9 to the high part of the ballast is a big loss in spark energy down the road.
