Wiring Help (1995 Crossflow)


Gridgway

Recommended Posts

I successful wired up the wires I had split to take the wings off - bullet connectors - yuk.  And after a small false start that all works.

However my fog lights don't work.  The bulbs are good, the earths from the bulb fittings are good.  Then I tracked it all through to the switch, then to the side of the fuse that feeds the switch, all good.  Fuse ok.  However the other side of the fuse doesn't have12v.

I made a slightly dodgy bodgy fuse that just has two wires, one soldered to the top of each fuse "leg".  That's how I traced continuity all the way through to the bulb.

Now I'm stuck.  I don't know where the main 12v for the fog lights comes in.  It looks to me that the next step is to get the fuse box off and poke around the back of it, but that feels pretty horrible.

So all thoughts welcome from anyone who has knowledge here!

And also to add.  I don't know when the fogs last worked.  I've not checked them before.  The car came with an MoT from two owners ago.  Not sure if a foglight is mandatory for that age of car - I think so, so it's fair to think that they must have worked then.

Thanks Jonathan, I do indeed have all the diagrams.

I #think# I tested them with side and then side and headlights on (and none).  But that was an hour or two ago.  Do you think the headlights need to be on for the fogs to work?  It makes sense for it to be something that simple!

You are a genius!  I was sure they shoudl work independent of the headlights, but I was wrong and I clearly didn't test that!

As you were everyone, nothing to see here!

Now if someone could tell me why my reversing lights don't work that would be fab!  They didn't work before and I had to change the switch on the gearbox and rewire that end.  They still don't work!

I think April 1980 is the date when fog lights became mandatory - but if it is fitted to an earlier car then it has to work.  This sticks in my mind from when my 1979 ex-coastguard Land Rover (with all the extra lights fitted) failed an MOT because one fog light lens had a crack in it...

Reversing lights: 

The circuit is usually earth switched.

It sounds as if you have a multimeter...

How many terminals are there on the switch in the gearbox?

What colours are the connected wires?

Have you swapped any lamps for LEDs?

Are you testing with the ignition ON?

The reversing lights are tomorrow evening's job.  I need to remind myself how they are wired.  I think... two connections to the lights.  So I think +ve to the lights, -ve back to one terminal on the switch on the box and the other terminal to the body.  Starting point is to test the +ve to the lamps.

Perhaps that needs the headlights on as well!  That would make life easier to solve it the same way!

Early reverse switches had one connector and earthed through the body of the switch. Later switches had two connectors one of which needs earthing (doesnt matter which)

As Jonathan states the switch connects to earth so you should have 12v at the lamp and switch (if the bulb is sound)

Thanks Ian.

The old reversing light switch was one contact, but didn't work.  The new one I put in has two connections so I made up a lead to go to earth.  The switch worked with the engine and box out so I hope it still does as I don't want to take it all out again to change the switch!  I'm sure that's not going to be necessary though.

I thought I'd have another go this evening, but I've had to go out to a "do" I'd forgotten about so it'll have to wait.

So without any changes, just faffing about a bit, one of the reversong lights works.  It's the lhs one which is further forward in the wiring circuit if that makes sense.  So the fault on the RHS is downstream of that.  Most likely thing is just the rhs bulb.  So I'll have another look tomorrow.

With the lighting sorted, there is very little to do to get it ready for the rolling road for tuning.  Not long now!
