Chrysler made many electrical changes from the 1960's to the 1970's. It is important to get the wiring diagram for your specific car. The factory wiring diagram for a 1971 [VL] A body is hard to read. [basically 2 pages]. And the aftermarket diagrams [Clinton's etc.] aren't always correct.

Your car: points gap = .017 ----- timing = 2 1/2* ATC ----- non adjustable hydraulic lifters

I use a 12V incandescent test light for most old car work. Get a good one with a long cord and alligator clip. And check it on the battery terminals every time you use it.
