WIRING UP ALERNATORS WITH EXCITER WIRE

Post by ludacris »

IT IS A FORD 302 ALTERNATOR AND IT HAS A WIRE FOR
S
AND
L

ALSO A 24 VOLT BOSCH ALTERNATOR WITH CONNECTION POINTS OF
W
D+
D-

AND B+

WOULD BE NICE IF SOMEONE CAN MARK WHERE EACH POINT OF CONECTION CONNECTS TOO. THANKS IN ADVANCE.

That will sort the Bosch one for you. Not sure on the 24V one, sorry.
This is not legal advice.

alternator connection points

Post by mgundle »

24V Alt
B+ is battery
D+ is Warning Light
D- Is Rectifier earth which dont worry about
W is star point which is directly off the windings of the stator generaly speaking its half the voltage of the alt.
used for running relays and taco's not for large loads.

I did hear of someone putting 12 volts into the W on the 24v alternator which acted as an exciter wire.
