Many TR6s with internally regulated alternators are wired for 5 electrical terminals. The 5 terminal alternator design is obsolete and is now replaced by a 3 terminal type. The following wiring instructions, provided by Lucas, outline the conversion procedure from the '5 terminal' to '3 terminal' type.
- Disconnect battery.
- Cut off wiring terminal plugs from alternator wiring.
- Remove and discard link wire (see illus. below).
- Remove wiring harness tape approximately 1 inch.
- Slide small insulator over remaining IND wire (brown/yellow), and solder to the small terminal.
- Slide large insulator over positive lead wire (brown/white), and solder to the large 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.
