Well I didn't unplug the external reg, as the car wouldn't start at all otherwise. Does this kill the internal reg or actually damage the alternator itself?

Tom,
Here is a copy of an old post on how to convert to a Bosch IR Alternator on a 1600 from either Hitachi or Lucas ER alternators.
You can't hurt much with a Bosch except if you don't pull the plug connected to the external regulator.

Disconnect both battery terminals
_Alternator wiring (Bosch IR)
_
White/Red (thick wire) > B+
(I recommend if you have over 300w headlights & a mega amp etc that you run an extra 6 mm shielded wire from B+ to the Starter Solenoid as the stock 510 loom wire is rated at 35 amps and turns into a cigarette lighter with the high draw and charge that your Bosch alternator is capable of.
Yellow > Ind
Black (-) > (E)arth (some Bosch don't have a terminal so just use the screw on the back that's for a suppressor.
White/Black (Field) > not used
_Suppressor
_Connect the barrel to the Alternator body and the wire end to the B+ terminal. A suppressor is not required at the old external regulator end so discard if one is fitted.
_External Regulator (Hitachi or Lucas)
_
*Important. Pull the connector plug at the regulator*
Make up a jumper with 2 male spades and bridge Yellow to White/Red in the plug _on the loom side_.
Original Aussie 1600 wiring details for info.
************************************************************
There are 6 wires in the regulator plug behind the battery.
1. White/blue - Ign
2. White - Batt (12v)
3. Black - Earth (ground)
4. White/black - Field (from Alt)
5. Yellow - Ind (from Alt)
6. White/red Ind (to dash CHG light)
Wires 5 & 6 are the ones that you connect when you convert from a Hitachi or
Lucas external reg alternator to a Bosch internal reg alternator but you
must disconnect the old external reg at that plug - it's that simple.
Connect battery and start your engine.
Check that the alternator is charging with a multi-tester and load test it with the lights on.

Subject: Alternator regulators
List,
If I fit an internally regulated alternator into a car that was
previously regulated, and botch it, can I damage the alternator?
I think I've damaged either one (or both) of the regulators- how do I
test for this and how can I fix it (bypass the damaged internal
regulator and use an external regulator for example?)
Cheers,
- Tom
