69 273 headlights wont turn on
Electrical Circuits
Wipe all this down with a damp cloth so it will be easier to see.
The heavy red wire with a connector labled A is the battery feed/charge line.
It should connect to a 16 gage fusible link. What I see looks like a repair that may or may not be made with fusible link wire.
This is a critical connection as well as an important safety feature.
An original looks like this. Notice the terminal going into the bulkhead multi-connector has a molded insulation that seals out moisture and dirt.
Bill Evans makes and sells this decent looking reproduction.
On the voltage regulator, it looks like two wires in a harness wrap connecting at the bottom.
I believe that is correct for '69. Both are probably dark blue and one should be 16 gage and have a white stripe (aka trace).
The green wire connected at the top goes to the insulated 'Field' terminal on the alternator.
When the voltage is low, the regulator lets current flow through the green wire to power the alternator's rotor creating an electromagnetic field.
When the voltage is high, the regulator lets no current through.
