D+ is for the exciter, alternator dash signal light and voltage regulator circuit. This must also be showing 12.5 volts when the engine is not running, but the ignition switch is on. If it is not 12.5 volts, then the battery may be flat, and the light will come on when the alternator is running.

For cars with voltage regulator mounted on the generator: Remove the small blue wire from the regulator; this wire will connect to the "D+" terminal on the alternator. Remove the two large red wires from the voltage regulator. If you are installing a stock 50 amp alternator, install loop connectors on both wires and connect both to the "B+" post on the alternator.
OK I know on the back of the alternator that the B+ is the main charge output to battery, and that D+ is another +ve feed that switches the dasboard battery light off after ignition. And also that the W connector is for a tachometer if fitted.
