Subject: TECH Re: Converting From Dynamo to Alternator
These are my notes from an article by Keith Calver on instructions according to Peter Calver.
Parts needed:
   bracket 12G1053
   pulley  12G1054
   fan     C37222A
   belt    GCB10825
  1. Disconnect battery
  2. Remove regulator box from car, carefully marking all connections.
  3. Remove dynamo, etc.
  4. Fit alternator, new bracket, and new belt.
  5. Dismantle regulator (use junk regulator if you have one). Remove coils and contacts. Remove connections to blade terminals.
  6. Solder links between terminals A, A1, and D, connecting all three.
  7. Solder a link between terminals F and E.
  8. Reconnect loom to correct terminals-EXCEPT-connect ignition warning light (brown/yellow) to terminal E.
  9. Connect alternator to loom: Large wire to large terminal (output), and small wire to small terminal (sensing).
  10. Reconnect battery
If I recall these instructions assume use of Lucas alternator and keeping pos(+) ground. If you convert to neg(-) ground, you need to make sure battery is installed correctly and that the battery connections at the ignition coil are correct.

Hope this helps.
