MAD electrical upgrade for 1973 Dart

Just did mine this weekend.. I just put both lugs on the ammeter on one post. and got rid of the firewall connections. I havent ran the alt direct to the starter relay yet.

Anyway I am running a MSD 6al also, Mine is being triggered by a unilite so it requires the ballast resistor. MSD has a lot of drawings out there for how to wire it up depending on your distributor. Likely your ballast was hot due to whatever short happened at the firewall or ignition switch.
