Console harness - what's covered?

[iani]

My car has a non functioning modern radio fitted so I thought I'd take a look at the wiring today, unfortunately some of the insulation has clearly melted so all was not well. In putting it back I have now lost my heater fan and I also noticed two taped off wires, Red/Yellow & a Purple/White. Given that there has clearly been some bodgery going on in here I was wondering whether I should replace the console wiring harness but I'd like to know what this actually covers before I shell out on one (Rimmers?). Has anyone fitted one of these? if so, is it straightforward and what does it cover?

Here's one from Maritn at just triumph http://cgi.ebay.co.uk/justriumph-MK2...1%7C240%3A1318

Give him a ring he'll have more than one for sale or will end it early for you.

If you need pictures just ask I'm sure we can help. As regards your fan switch check the wires are connected to the relay as I had this problem the other after knock the black wire of when replacing the parcel shelf.

Thanks Stuart,

Fingers crossed for decent weather next Saturday and I'll get a better look at what's going on.

I went to have a look at the heater relay today, pulled the carpet down and discovered that the previous owner had cable tied it to two of the wires on the main loom, not a brilliant idea. The fan relay connections all seemed sound but things have now got worse, I have no instrument illumination, no indicators (hazards are fine) and no O/S Main Beam (bulb replaced but no change). I am now chilled to the bone, depressed & hoping tomorrow is warmer.

I'll bet anything you have the sympathy of everybody on this forum, Stag wiring is simple and straightforward - until some bugger mucks about with it ! Good luck, Martin.

My old spitfire had most of the engine components wired up with household 3 core electrical cable.:shock:

It took a couple of weeks and what seemed endless amounts of the correctly coloured wire to sort out, but with the trusty Haynes manual and Patience it turned out to be quite an easy job, and very rewarding when everything worked once completed.

Hello Ian,

Just came in from reinstalling my heater unit, which entailed taking out the dash etc. so I have just been playing in the same area as yourself.

As for the taped off wires, I have them too. Purple/white are part of the courtesy light system. You might also find a Pink/white which was provided as a pickup for the radio. I can't find red/yellow in the circuit diagrams, but I have one, taped off, down by my left foot. By the normal Lucas convention it would be for fog lights. I haven't checked the front of the car to look for another end.

Nowlets try the problemsbit by bit.The items you list work from seperate circuits

I went to have a look at the heater relay today, pulled the carpet down and discovered that the previous owner had cable tied it to two of the wires on the main loom, not a brilliant idea. The fan relay connections all seemed sound You don't say whether it is working or not. If you pull on the switch for the heated back window the little light beside it should go on. If it doesnt check for power at fuse 21-22 and then you are back to the relay.

But after looking at the relay you have 3 other problems:all on different circuits. The common element is the fusebox and its connections, just behind the relay board. It may be loose connections if you are lucky. The fuse holders are riveted in place and can come loose, with loss of circuit.

No O/Side main beam: But nearside is working: Switching circuit for these is a line to the fusebox at which point it divides to feed two fuses. For your problem we are looking at contact 17 feeding through the fuse to 18. Check the fuse has not blown and then check for loose connections at the back of the box, just behind the relay board.

No instrument illumination: Check the dimmer has not been turned off. Then check whether you have LH side and tail lamps. if all is off we are back to fuse connectors 7 and 8.

no indicators (hazards are fine) Power for the hazards comes from an unswitched source whereas the indicators poweris initially switched by the ignition switch. This time we are looking at fuse contacts 3 and 4, especially if your stop lights are not working.

Hope this helps

Brian,

Thanks for your detailed response, I'll take another look and report back, it is highly possible that in pulling the carpet down the wiring at the fuse panel was disturbed.

Correct Brian. The 'other end' isdown near the washer bottle on early cars. Possibly behind the front valence on later ones. I haven't got around to looking for it on mine as I haven't fitted the front fogs yet.

Thanks to Brian's helpful suggestions I decided to start at the fuse panel, thanks to the carpet having been attached to part of the loom it looks like I pulled 2 of the wires out of the rear of the fuse panel, I now have my instruments, instrument illumination, indicators & O/S mainbeam back, still no heater blower so I may need a relay. Thanks for the responses, my depression has lifted...until the next issue crops up

I found the 'other end' of the Red/Yellow wiring behind the front valance, mine is a '76 car.

It's probably not Red Yellow, but Red Orange and faded - part of the RH sidelamp circuit

The taped off end above the console isn't faded, definately Red/Yellow, the wire looks the same to me, the sidelights work fine.
