Ignition problems?, in an old dodge truck

[JDmills]

I've been working at an 46 Power Wagon, making some improvements, and trying to get it ready for snow plowing duty here at the house..

I put a dodge electronic ignition system in it out of a slant six van, and have had a little trouble getting it to run consistantly.

At first it would start and run right off, but stall easily unless it was nicely warmed up.. Now it will start and run for about a second and then stall, and this will happen a few times until it refuses to start at all..

Wondering about a balast resistor.. but dont really understand how they work.. I tested mine and it's resistance is slighly higher than the repair manual calls for.. on the primary side, and maybe the same on the secondary side..

so maybe i should replace that? is there also a good test to check the coil? or suggestions as to how to discover more about this ailment.

Thanks
