HELP!!!Wiring issue with 73 Dart Sport
This is a very common problem here's how it works
You only have ONE source of switched power for "ignition run" also called "IGN1" under the hood
It powers the ignition system, alternator field, voltage regulator, electric choke if used, idle solenoid if used, and in some cars, some smog doo-dads.
THIS POWER GOES DEAD when the key is twisted to "start."
There is a SECOND power lead that is hot ONLY in the "start" position AND IT IS NOT the yellow start wire which activates the starter relay
This is a dedecated switch contact known as "IGN2" and is the coil resistor bypass circuit. It is normall brown and only goes one place............
Comes off the ignition switch, through the bulkhead connector, and goes to the coil+ side of the ballast resistor
=================================
What has happened is that in your stripping stuff out you left this hanging. You need to connect it to the blue "run" wires where you branched off to the MSD
IF YOU DON'T have one, go to MyMopar and download the 73 factory shop manual free. It and some other manuals over there came from the guys right here
