Amp guage maxed out.

THIS IS ABSOLUTELY THE WRONG ALT FOR THIS CAR! I went tru this twice on my barracuda. you need the squareback (1970&up) alt. if you haven't burnt your wiring harness yet your lucky. when people convert to the electronic regulator (and electronic ignition) the changes to the harness mimick the 70&up underhood schematic. problem lies with the parts store monkeys. or in my case ME. If you ask for an alt for a 69 Dart you will get the one designed for the mech regulator and it is wired differently and not compatible. it physically looks similar until you look and compare both. always ask for a 72& up Alt to get the right one.
There was a square back in it with the 318 and it got tossed because it was so ...dirty and old. Very stupid thing to do I see now. Then Lordco gave the shop what ever the computer tells them to give them as a replacement
