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.

"Smart alternators" they call them, don't they? I reckon it's actually the ECU that does smart controlling. :)

I really should've removed the leads anyway. The shock was via the 1 Megohm input resistor. The initial open circuit voltage was the full 240v. Since I closed the loop, it dropped rapidly so was non-lethal.

Compare that with my experience with mains electricity. I've been electrocuted countless times, lethal and non lethal, since I was a child and at least three times it was the brink of death experience. First time I managed to touch the live and neutral wires which kept cooking into my palm while I was trying to break free(don't ask what I was doing with open main electrical wires. :) ). Luckily the plug came out of the wall socket and I had a wire embedded in my palm. Second time from a TV. Third time from an old fluorescent desk lamp. That was few years back with a faulty lamp. I had hole burnt all the way into the bone on my middle finger. I was able to break free from the lamp by shoving my leg in between and pushing the lamp away.All those three lethal times the electricity managed to pass through the heart without stopping it.(But, must have bypassed the heart due to some luck). Those kid days are over and now I'm super careful. Especially, I'm super careful about poking my hands into the running engine. :)
And of course, I don't poke my hands into live electrical wires no more either.

Hehehe, I know what you mean but... Lucky your a Hindu, others only get one shot of lethal electrocution

It's not lethal if it doesn't kill ya!
And no one living has ever been electrocuted

Well......it was lethal. I went to the other side and came back. ;) :D
It would've been lethal, if that was you. I got some kinda "lucky" resistance to electricity. ;)

If your not Hindu, you couldn't get reincarnated.
If you didn't get reincarnated your dead.
If you were dead and now your not then "Welcome back and I'm really sorry about all those Jesus Jokes but can you do anything about all them peados in the black robes?"... Hehehehe
