Posted September 24, 20231 yr comment_657435 I have put new connectors on the voltage regulator wiring. I wired the connectors exactly as they were before going to paint. One of my questions is why are there only 5 wires coming from the wiring harness, but 6 coming from the voltage regulator. The white wire with red stripe (IMG_7889.jpeg) from the voltage regulator does not connect to a wire from the harness. Also there is a single black wire with white stripe (IMG_7890.jpeg) coming from the harness that does not appear to connect to anything. Anyone know what the wires purpose is?

September 24, 20231 yr comment_657439 You don't have a stock voltage regulator. The wiring diagram shows 5 wires. Sense means it is reading battery voltage. Field is the wire that it uses to excite the field of the alternator. Neutral is the neutral of the alternator. The L terminal isn't used, but it would be for the Lamp signal. If it was used, it would connect to a bulb in the dash, and the other side would have a switched source. If the alternator wasn't charging, the bulb would light up. It's a shame they didn't use it. The BW wire with the bullet connector is for a condensor that isn't shown in the wiring diagram. It resides around the VR.
