No spark

Stand by........

Ok..........go to Mymopar and download the two factory service manual volumes, you want the chassis manual for this not the body manual

You are going to have to be happy with a Dodge manual in this case

MyMopar - Mopar Forums & Information - MyMopar Tools/Reference

which leads to here

MyMopar - Mopar Forums & Information - Service Manuals

Then go to the wiring page

MyMopar - Mopar Forums & Information - Mopar Wiring / Electrical

You end up here

MyMopar - Mopar Forums & Information - Mopar Wiring Diagrams 1972 to 1976

and save the two files for the "these are" AFTERMARKET NOT FACTORY wiring diagrams. They are "handy" and "easier to follow" sometimes, but are NOT always complete

Now let's go back to the 73 Dodge manual you downloaded. Go to page 8-128 which is the engine bay wiring for a 73 Coronet/ Charter, and look there in the upper right hand corner

Notice on the right side end of the ballast, (in the photo) THE TOP AND BOTTOM are jumpered together with a short wire. Find this on your in-car ballast. THAT POINT is where you jumper in 12V from battery to "hot wire" the ignition. THIS MAY BACKFEED and light up the gauges

If your alternator is REMOVED make CERTAIN you tape off and safe off the wiring going to it

THIS STUPID NEW SO CALLED NEW AND IMPROVED SOFTWARE ABSOLUTLEY SUCKS!!!! for someone trying to answer a serious question. You CAN NOT READ the op's question while you are attempting to post an ANSWER!!!!
