With the ignition key on, is the charge warning light on? Meaning lit.....

In the Bentley it says Terminal B+ is supplied battery voltage from the battery directly. Terminal D+ is supplied battery voltage via the charge warning light when the key is on or the car running.

On page 121-4 Charging system checking

#1 Turn ignition key on. Check that the charge warning lamp comes on

NOTE-
If the warning light does not come on, repair any wiring or bulb faults before continuing to check the charging system!

Maybe the bulb is out which completes the circuit to D+........if not, recheck your wiring......
