Alternator Not Charging After Changing Wiper Motor

I cannot see anything there that should have affected things

What do you have for alternator / regulator, that is, are you still using the old 69/ earlier style?

If so, unhook the field wire, and hook up a clip lead to the field terminal. "Scratch" it on the alternator output post and see if you can see small sparks in dim light. If so, hook it up temporarily, start and run, and watch the meter to see if it charges. Don't leave it hooked up longer than to test, as it could run the battery down.

If you see no spark, either the brushes have lost contact, or maybe the main charging wire lost contact in the bulkhead connector.

Use a test lamp or voltmeter to see if you have battery voltage on the alternator output stud. It should be hot at all times.

I believe I can see part of the regulator up by the firewall. It appears the two wires you have pictured should hook to the regulator?

The "push on" connector should be switched 12V "ignition run" and the green wire hooks to the regulator screw terminal and goes to the alternator field terminal
