Thanks for that, it's the wiring conversion I need to study.

There are loads of suppliers and most will contain instructions on how to modify the control box etc. It is all just linking some connections and removing others.

I used a kit from Wins International. Dead simple.

Thread drift sometimes makes searching confusing, and we all have our own way of doing things.

really simple. On the control box:

1. Ditch the earth

2. Connect F and WL

3. Connect the rest of the cables together. This is a chance to add fuses if you so wish.

Thank you very much. That is really helpful.

Now, at the Alternator are three terminals together two wide one's and a normal small one.

All male spade connectors.On the loom are three cables, Brown with yellow tracer , large female spade connector.Brown with green tracer,  small female spade connector and white with small female spade connector. Do you have instructions for this end as well please?

Not with my wiring diagrams, and no wish to get this wrong....

However, the 2 large terminals on an ACR alternator are joined, and are the charge outputs. The brown/yellow is the main charge wire, so that fits on the big terminal. 

I think the brown/green is the old field wire, so connects to the small alternator terminal. But check

White?? that is an ignition switched live if original. No idea where that has come from.

Finally, as your new alternator probably kicks ouy more than the dynamo, it is a good ide to get a length of 30A wire (similar to the thick wire you already have) and fit to the 2nd large terminal, and attach direct to the battery positive or the solenoid terminal that the battery supplies. This will stop te original wire ever getting overloaded, and improves charging.

The topic has already been answered in the above posts but I've bookmarked a great explanation on a New Zealand site that I've referred to many times, so here's a link:

Again, thank you very  much. I believe the white wire goes to the coil positive side.

Many thanks.

some have a batery voltage sensing wire to aid control of the charge 

not used by triumph but often found on vauxhalls of the era
