Central display

Maybe just stating the obvious, but have you tried just dissconnecting the radio?
Leaving the plug dangling should bring you back to how it was with just the cut wires. Right?
Just a simple test before you go tearing into stuff that could be working ok.

Hi, this is a picture of the connections going into my radio.
The white connector is for the speakers, the black one is the important one which I'll explain.
Pin 1 - no connection (nc)
pin 2 - orange (9004C) This is a communication wire which is
twisted with the wire going to pin3.
pin 3 - light blue (9005C) . Comms (see above).
pin 4 - green (XE3) This is a switched 12 volts for the comms.
pin 5 - nc
pin 6 - grey (A07B) This is a another switched 12v for the radio.
pin 7 - white (B11D) + beige (B11B) This is a constant 12v feed and
also supply's the Multifunction display.
pin 8 - green/yellow (M840) This is the ground supply (Negative).

If the display is fading out It is due to having no supply. Make sure there is 12volts on the beige wire (pin 9) at the Multifunction display connection.
Also make sure if the twisted comms wires are disconnected in the radio bay, they are safe and are not shorting to earth etc.

Let us all know how you get on and what the result is or if you require any more help. alut:

Thanks for the wiring rundown Rustcrat. Being a sparky, I shouldnt have too many probs chasing that through, its just the lack of a diagram ............
I'll let you know how I get on.

p.s. I like a drop of John Smith smysel - the extra smooth is my tipple!!!:brickwall:

Yep - tried that!:brickwall:

Jules, if the wires don't match up, PM your vin no. and I'll get the correct drawings as the ones I got the info from are for my van. tudy:

1st chance I getThanks for that. I'll be out there with my trusty mm

hi again. Checked wiring out as per your set up and found that while I seem to have most of the colours present, almost none were in the same locations as you described. Also, significantly, I found that at switch-on there was just over 9v on pin 9 (not beige) and just over 11v with the engine running. However, the display still faded away as before and the voltage - engine running or not running - faded simultaneously with it and levelled out at around 2v.
I dont suppose there's a rechargeable battery somewhere (perhaps to hold the settings like a CMOS in a PC or push-button radio for example) that cant hold its charge anymore, because while the info is still visible, I can set the time and date etc but after its faded out, next time those settings are all gone and need to be reset

[Rustscrat]

Ok, looks like you are missing a supply.
Check pin 7 on the radio connector and see what you get.
Are there two wires spliced together in this?
If the supply on this pin fades like pin 9 on the display then check fuse 4 (20Amp) on the Bsi.
This is a permanent 12v supply.alut:

Let us know how you get on.:thumbsup:

Hi Again

the pin layout looks about the same but the colours are somewhat different.
There is a permanent unchanging 12V on pin 7 and yes there are 2 wires going into pin 7 fed from a single white.

[Rustscrat]

Pin 7 on your radio is connected to pin 9 on the clock display.
This must have been cut if it doesn't ring out with your meter. tudy:

yep steady 12v present on pin 9 and its fed by a pair who are fed by a single white. Dont see any comms wires any where. Guess I still need some direction...
