65 dart not charging with new alternator
Assumptions...
- Your current bad alternator is the square back one in post #1
- The round back photo is a stock photo of a single field wire round back alternator
- The parts store gave you an alternator based on the car not the current alternator setup.
- You have done some testing by shorting to ground some of the field wires ( you may have damaged the voltage regulator)
At this point you need to post photos of your voltage regulator
Your current alternator and wiring
And the replacement alternator.
That way we all are on the same.
My best guess as was noted in earlier posts...
Your alternator and charging system was changed at some time to the newer style that uses an electronic voltage regulator and two field wires on your alternator.
You purchased an alternator for the origional car which would have been a mechanical regulator and only one field wire.
After we see photos we can advise, but I would unhook the field wires till we know what you are working with
