Alternator Terminal Conversion
Many British cars are wired for 5-alternator terminals. As the 5-terminal alternators are now obsolete, 3-terminal alternators may be supplied. These wiring instructions, provided by Lucas, outline the conversion procedure. To wire a 3-terminal Lucas alternator in place of the now obsolete 5-terminal alternator, use plug kit #540-280 and proceed as follows:
-Disconnect battery
-Cut off wiring terminal plugs from alternator wiring
-Remove and discard link wire (see illus above)
-Remove wiring harness tape approx. 1 inch
-Slide small insulator over remaining IND wire (brown/ yellow), and solder to the small terminal
-Slide larger insulator over positive lead wire (brown/white), and solder to the larger terminal
-Separately tape back onto harness, the brown and black wires not used as they are no longer required
-Connect the small brown/yellow IND wire to the small terminal on the alternator
-Connect the large brown/white positive lead to either of the two large terminals on the alternator.
-Re-connect the battery.
