69 dart wiring issue?

Here's the deal, I had a slant 6 non electronic ignition, swapped out for a 74 318 with electronic ignition. I put the electronic ignition into the 69 dart with the 74 ballast resister and voltage regulator.
The car runs great but I have gone through three batteries, thinking that there was a short or draw when parked. Now I thinking I'm cooking the batteries up when driving it? I have the 74 and 69 wiring diagrams. There is one blue wire that is on the top of the middle clip on the fire wall that I'm not sure where it goes, I have it tied into the main red that goes to the alternator. Anyone have a 69 with electronic that they could check.
The reason I'm thinking it ids cooking the batteries is the ballast resistor gets red hot burn your finger if just drove a mile or so? Like I said I have drove the car like this for about 2000 miles with out an issue except after being parked I find the batteries is dead.Thanks for the help
