Everything replaced... Alt. still not charging.

1970 Plymouth Duster 340

Original issue: after sitting for a couple months, engine would crank but not start... when I leave the ignition forward and jump start at the starter relay engine would start and run. My first thought is the ignition switch went bad.

Replaced the ignition switch.

Now the car cranks but no spark... replaced the Ballast resistor.

we now start and run.

BUT now after running for an hour, the battery is dead.

Pulled negative battery cable, engine dies.

Alternator is not getting any power.

replaced alternator and voltage regulator and still not getting any power to the alternator.

last thing I replaced was the starter relay as the positive wire runs through this unit and now have power running to the alternator BUT still not charging and dies when negative terminal is disconnected.

I have a 71 dart that was a known good source (charging system worked) that I have been pulling/ swapping parts with for testing and nothing.


sry for the story but what am I missing?

is it possible the gauge inside the dash got disconnected while working on the ignition switch? possible error with ignition switch? this fusible link I have been reading about?

no damaged wires and the bulk head connectors going into the fire wall are in good condition.

this all worked the last time I drove it...

any help would be greatly appreciated.

thanks!
