Are you sure?  Are you maybe thinking of something else?  Bentley shows a
perfectly ordinary SPDT relay, energized through the alternator D+ terminal
and grounded by way of the starter solenoid (50 terminal on the ign
switch).  This last bit is to my mind unnecessary -- it prevents the relay
from closing while you crank the engine, but I've never heard of a Bosch
alternator that would charge while cranking so I think it's moot...

Bentley 97.32b track 26...
