Hello! New to this forum and I could need some help.

I bought a Lancia Voyager 2.8CRD a while ago (town and country but with Lancia badge?). I accepted that the battery warning light was on, the previous owner said that it was a cable he didnt connect when he changed the alternator so now im trying to fix this, I dont like warning lights

I fixed a workshop manual and there it says that on the diesel version the alternator is regulating itself and if the connections are broken it will function but in default mode. I checked the engine compartment and saw this:

The connector is just hanging loose. It doesnt reach the alternator from down there but this is the only contact I could find. Maybe someone didnt put the harness correct when they serviced something?
But even if it reached, the alternator have a 3-pin connector, i found a pic on a car parts site:

And here is the wiring diagram that should describe voyager 2011-12 charging:

Now i need your sharp brains

First of all, the colours on the two wires doesnt match the wiring diagram, they are red and green on the car and red/violet and brown/grey in the diagram?

If understood it right, there is one wire that makes the PCM and alternator communicate and one wire that sends input to the PCM.

Im thinking it should be possible to measure this? If the alternator should be connected like the picture above, then i would have 12v on the two "D" when the engine is running?

The pin in the middle named "LIN" should be the communication wire.

How can i measure the two wires in the engine compartment? Do i get 12V in the communication wire? In both?

Can someone tell me what the shorts mean in the wiring diagram above?

ALTR SNSE FLNK TO MOD =? (alternator sense......? communication cable?)
ALTR FLD FED =? (alternator field feed? the wire that should get 12V from alternator?)

My theory is this: If the red wire = red/violet then this is the communication wire that should sit in the middle on the alternator and the green = brown/grey then should be the input to the PCM and should be connected on any on the "D" pins?

Im hoping that I have explained my problem well and hope U can read my english Thankful for any thoughts! /Roger

 

I came to the conclusion that my car have the correct alternator but the correct wire is missing, I have looked where I can reach but cant find it. Is there anyone here who has a Voyager 2.8CRD and can check where the wiring to the alternator is connected so i know where to look? Pictures would be great.

 

I will answer myself if someone should have similar problems:

The case is solved. Its not easy to find a wiring diagram for the 2.8 diesel but at last I found one.

The three pins on the alternator stands for Dummy-LIN-Dummy so only the "LIN" should be connected.

According to the wiring diagram there should be a wire between ECM pin #93 and the LIN connections with white/orange.

Found the cable by the ECM but the other end is impossible to find if i dont remove a lot of things.

Cut the wire and made a new cable to the alternator and works perfect!
