Alternator wiring.

[Cam]

I have a 3-wire alternator.

The two fat wires are connected together in the back of the alternator (you can see if you take the alternator off). There are two wires to spread the load.

So, connect the two fat wires together and then connect them to the +ve of the battery (or battery side of the starter solenoid - it's easier).

Connect the thin battery warning wire to the wire that goes from the regulator box to the dash charging warning light after it has been disconnected from the regulator box.

I re-wired my regulator box at the back so that the internal components were not connected and the box just acted as a junction box.

The connections to the dynamo were left on the regulator box but cut from the loom at the engine end (dead wires) and the terminals A and A1 were hardwired together in the back of the regulator box in order to provide the accessories with power.
