Singapore 110 FFR alternator wiring

Hi all. I'm new to the group go easy!

I have a 1985 110 FFR form Singapore just recently my battery light came on and Im trying to work out how it's wired. Has any one got a wiring diagram for a Singapore Landover as there wired different to others.
I have a single 24v 90a alternator generator.
4 wires coming off Inc positive negative and 2 small ones brown and white and brown and black

Behind the seat is a shunt for the amp meter
And another box

Any help would be greatly appreciated

I'm afraid it's highly unlikely that anyone has one.
The Government of Singapore release zero information, so your best bet is to find someone who has hands-on experience with an SG Landy, or perhaps write a letter to the the division of JLR that were responsible for this contract, quote the VIN and ask for a wiring diagram, but it's likely that JLR will be under NDA and won't be able to help.
I do mean a proper letter, Signed For.

Your ammeter is it centre reading eg 100-0-100 or zero reading eg 0-100? That will tell you in the first instance that it is wired to measure charge & discharge from the batteries or in the second instance merely telling you the output of the alternator.

I am not sure that I have understood what your pictures are in relation to the text. It seems that the back of the alternator has the three thick wires & the two thin wires with tracers. Between the terminal strips are two shunts (zig-zag metal strips) stacked with a space for cooling. The thin wires from this go to your ammeter.

This other box behind the seat that you call the shunt box, looks like a distribution box & I can see no shunts in that view.

The first picture is hard to make out any detail of what I assume is the alternator. I don't recognised anything in that view, can you show us a view of the whole alternator & any nomenclature plates on it.

Took it off today looks like regulator is part of it

Hi just a quick up date managed to solve wiring issue ihe exciter circuit cable had only 8v so cleaned up as many earth point is I could fine and cleaned all connections and got 24,5v all back up and running.
Did however find that in its wiring some altanator wiring goes through a starter inhibitor relay so with big plug removed on the alternator you can't start it just thought it might be some use to some one.
If anyone comes across a spare alternator like mine I would be interested in buying it as there like rocking horse . Many thanks for your help
