I'm getting a tad confused here, so a little help is needed.
Firstly, the landy has no original wiring left, it's all gone, i've replaced most of it and still working through other areas over the next few days.
My issue i'm stuck with is the alternator and it's role as a charging system, i've googled, looked on here and come up with a few answers but i'd like a nice definate answer if anyone can help as some answers don't quite add up to what i need to know.
I have an alternator ( from a 19J engine, bolted to the 200tdi block ), this has 3 wires from the rear.
If anyone can help with the above points, i'd be most grateful.

I have an alternator ( from a 19J engine, bolted to the 200tdi block ), this has 3 wires from the rear.
- 2 of these wires ( thick brown ones ) go to the starter motor, is this correct? I'm assuming it is as that's what the old one's did before i removed them.
- the 3rd wire goes into the dash area, and here it stays at the moment as i can't work out what i'm trying to acheive with it.
- From what i can gather ( i could be wrong ) is this cable goes to a light ( charge light ) from there it then goes on to the ignition ( switched, ie on first turn ) , but where after that? Is the point of this 3rd smaller wire to provide 12v to the alternator to get it to begin charging?
- I have a volt meter in the dash, this reads 12v when the engine is running, usually it's over 14v, but as i'm not charging the battery i'd expect this, but do i need the light if i have a visual on the volt meter anyway?
- I also have an inline resistor, do i need this anywhere on this route? ( i'll use a standard 12v interior light bulb if i can )
- According to the haynes wiring diagram, if i use the resistor directly after the alternator, then it also feeds the fuel shut off valve in the Injection pump, is this needed or can the the fuel shut off valve receive standard 12v from the starter/battery?
If anyone can help with the above points, i'd be most grateful.
