74 Challenger 318 car.So far I have had the battery and alternator checked both good. replaced the voltage regulator and ballist. I found that I fried the wire coming off the alternator going into the bulkhead so replaced it with another wire with a fuse in it. still coming out of the alt im pulling 11.7 volts the battery shows 12.2 and discharges. I unhooked the wires under the dash going to the ampmeter they were fine, not sure what to do with those wires so i left them unhooked. I ran a bypass wire from the battery lug on the alt. to the starter relay switch and still NO CHANGE..any thoughts. I believe this all started after I hooked up the msd ignition. I double checked that hook up and its right..
