'71 240z Voltage Regulator Wiring

[GregD]

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?

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.

Thx for the help Steve.
