Dave :
I don't know where the article is, but the process is really easy (assuming
your TR doesn't have any electronics, like a radio <g>). Basically you :
1) Disconnect the battery.
2) Switch the two wires at the coil (there is some debate about whether
this is required.)
3) Switch the two wires on the back of the ammeter (otherwise it will read
backwards).
4) Reconnect the battery, with the connections switched.
5) With the engine running, open the regulator cover and manually close the
cutout contacts. (If your cover doesn't come off easily, momentarily
connect a wire from the D terminal to the hot side of the battery.)
6) Replace the regulator cover.
You're done !
Nothing else on a early TR cares about polarity. The business with the
regulator is to "polarize" the generator, which creates the residual
magnetism it needs to start up the right direction. The heater and wiper
motors use wound fields, so will still run the right direction.
