Alternator Warning Lamp Circuit Question

[Yendor]

I've had a quick read through this, and am happy to say it is all well above my head and I understood next to none of it.

One thing I didn't see mentioned though, and perhaps I missed it, but is there any difference between different alternators in the way they excite and regulate and the circuitry needed? I only ask because I believe Dom has upgraded to a 110/120amp EF Falcon alternator, and I'm not sure if it's been taken into account (or if it needs to be, or makes no difference perhaps). If it's been taken into account already or doesn't matter and I've missed it, my apologies.

Yes it covers Dom upgrades. It basically covers the older style alternators with the two small wire connections "S" and "L". They all work in a similar way just what and how is done inside the regulator is different between manufactures. For example some switch positive to the field coils and other switch negative.

The later model alternators that are fitted to the Y62 and Navara's are different as they are also controlled by the engine computer.
