Re: help with alternator wiring

Do you mean the wire that goes to the CHG lamp on the dash? That wire comes from the Datsun external voltage regulator.

The 4A engine probably has a internally regulated alternator. In this scenario, connect IG terminal to ignition (say the coil + wire), then connect L terminal to dash lamp. Examine your old voltage regulator engine loom connector. It will have six wires, one of which is the dash lamp wire. In older 1200s (1972 for example) and newer 1200s (1992 for example) it is white/red stripe.
