'65 Dart-Lights flickered, lost electrical, loud bang, car died

If you lost all electrical power you have likely failed the master fuse link, which is the only protection the system has from some failures.

You can get wiring diagrams which are somewhat useful at MyMopar:

Wiring diagrams start page 8-96 Since this is Plymouth, you want model AV-1 or AV-2 for Valiant

Engine compt. wiring is clear down page 8-109

If you look at diagram "B" from MyMopar, find the starter relay, and from the top terminal, the left of the three wires you'll see is the fuse link which feeds through the bulkhead to the interior of the car.

First thing I'd do is unhook the alternator output wire at the stud, and tape off the wire. Then check and repair the fuse link. Unhook the battery ground while doing so.

Next, you want to find the short withOUT causing more damage. To do that, unhook your battery ground, and hook a test lamp in series. What this does, is any draw on the battery will show as a light, and nothing can "blow" as the lamp limits current. Make sure everything in the car is off, including the dome lamps, and see if you get a light at the test lamp.

By the way, a "big" lamp is better than smaller (wattage) for this purpose. A stop lamp or even a headlamp works well.

If the lamp does not light, touch your unhooked alternator output wire and see if it causes a light. If so, the alternator has internal problems

If the lamp lights, start by unhooking fuses one at a time in in the car.
