Any connection between charging issues and ignition?

[astat1]

I followed the gracious replies and think my faulty charging problem was resolved with getting a better ground at my voltage regulator and cleaning multiple contacts. Though I am awaiting a new harness and alternator.  I was getting a non-charging condition when my car got up to temp (180F) but was fine at startup. At the same time this was happening my car began to run very rough/dying at idle. This also seems to have resolved. My battery is new and fully charged so even if the alternator wasn't charging, the car should have not been affected by a no-charge state.....right? Is there any connection with spark and charge or is this another electric gremlin? Thanks

definitelly, with low charge conditions you will have also poor spark and ignition module response. With power fail, Ign modules tends to overheat and melt the back. On local experiences, everybody down here in Venezuela ended changing to Ford modules and Chevys alternators, without know saving the poor charging condition ( where that is the only true about Mopar fails ), Mopar modules get better, or in fact SIMPLY the right response.

That does happens also with MSD modules... poor power source gets a faulty spark response ( we already tested that in a Cuda of a friend of mine with a low charged batt )
