That is old, not seen remote voltage sensing for a very long time. All alternator regulators sense at the alternator now.

I know its bloody old. That's why they left it (the thin brown wire) disconnected when the then new unit replaced the original Lucas one.

Sooo, Figured what the extra wire that had been left disconnected is. Its the battery sensing one. The early A133 Lucas alternators were battery sensed ones. The newer ones from what i can understand are machine sensed. The brown thin one would...

TACR2 by any chance ?

Nope hehe. First year of the official Rover 4 door Range Rovers i think. Its an 82. It was registered in Germany. The German Fire Departments seemed to really like the Rangies. They began using them in 74 i think. Not a TACR2 though lol.

Indeed it does. The V8 statement is indeed true. I think the rev drop I am seeing or shall I say listening is enough to cause discomfort if you know what I mean. Gonna replace the loom and alternator and report back. Cheers!

Hey there, Thanks for the great info! Got ya. Yep indeed the later ECU systems do have the rev increase facility. What I am gonna do since I will have them at my disposal, I am gonna put the new alternator and the harness on the Rangie...

An alternator under load takes a fair bit of power but with a hulking great V8 driving it, I wouldn't expect much of a drop in revs really. I have no idea if the drop in revs you are experiencing is normal for that engine, needs someone who...

Revs dropping as the load on the alternator increases is entirely normal. If the revs drop too far then the ignition light may well illuminate or flicker. If you increase the revs it should go out. The later Classic Range Rover was fitted with a...

I see. That's how I had it cleared in my head too. Just wondered whether you meant something different. Couldn't it also be a case of a weak alternator causing the rev drop? As it's not compensating for the load thus robbing power from anywhere...

Hey there, Thanks for the response! Got the diagram. The brown wires go to the starter. The brown / yellow to the light. The brown ones don't have a relation with the ign light. It should come on when the key is on the second position and...

Hey there, Here again as i have been chasing what i think must be a charging / alternator or possibly engine harness wiring harness issue. I realise thats 3 categories each extensive on their own. So what i am faced with is a rev drop (sounds...
