Electrical Fun

[Lloyd Barnes]

Working through my final list of pre SVA items now. Only 40 odd minor things left to do! A few that are currently causing heartache

1) wiper motor not parking - used to but on the wrong side, so i moved the parking ramp round. now doesn't park at all. Guess its all coming off again!

2) fuse for washer motor blows as soon as you activate the lever -

3) no dipped or main headlights, although sidelights work, no fogs either.

think I may have the column switches wired up wrong?! Time to get the old multimeter out. Damned cold to be sat in the garage figuring this lot out The thought of summer on the road is keeping me going tho!

This might help, I'm fairly sure it's right, but it's worth double checking as you go through.

Hey Andy. Yours and Daves were the two diagrams I used as I went through. Sure they are right but the numbers on the switches are very small and I've probably buggered it up somewhere along the way.

I'm sure the headlights and washer problem must be related to this as its really the only thing I can see it possible to get wrong.

I'll go and brave the cold and have another go! (probably nothing will be working in a couple of hours! )

Have you just pushed the loom wires onto the stalk pins, it is possible to fit the loom ends into the plastic connectors from the Sierra, that is what I ended up doing after the SVA man kept pulling wires off

sounds a good idea, might follow your example. Have to say at the moment I'm totally baffled. Taken the light/wiper stalk off and checked the wiring against your diagram. Had an earth come off which I replaced, this fixed the washer problem.

However can't find whats wrong with the dipped/main so thought I'd tick off an easy one and fit the intermittent wipe relay. That doesn't work but the headlights are now permanently on I'll start again. Had another look at the Dax wiring diagram which confused me further. Says the blue wire is the feed to the lights for example, yet your diagrman shows it on the wiper relay Also have a stray black/purple wire in the loom which I can't find any reference to at all!! I hope they haven't gone and changed the loom or something (Sure it just my ineptness really!)

Black/Purple is the horn I think and there may be two, one for the wheel based horn and one for a stalk based horn. IIRC I had a problem with the headlights, can't quite remember what it was though although it could have been the connector between the loom sections.

that might explain the spare wire. I have two purple/blacks which work fine for the horn, and then one black/purple which comes out of the loom along with 2 earth wires.

I'll start again, have probably missed something obvious. What makes it more difficult is that there isn't actually a wiring diagram only a list of what goes where. So if something doesn't work you have to figure out what the circuits doing before you can test it properly.

For example is the headlight light switch providing an earth or a live to the circuit? I'm guessing probably a live but it would be so much easier with a proper circuit diagram.

Andy, nice tip about the connectors, much better solution than just pushing them on. However I still have a problem.

I still can't get the headlights to work. Have rewired everything as per your/Dave's diagram (was all correct apart from the dropped earth.) So tried putting a 12v feed to the blue wire and hey presto, everything works perfectly!! Lights come on and dip/full beam switch works fine.

Its as if this wire should go into the headlight column switch and be fed a 12v supply from the switch. Your diagram (and Dave's is exactly the same) shows this wire going to the additional relay. Thought this was an intermittent wiper relay? Have I got this wrong and its a relay for the headlights with the column switch switching an earth to energise it? Help!!! (am also bl**dy frozen but I refuse to give up!)

Checked and my loom has a space in the relay block for an additional relay? Is this where the intermittent relay actually goes

[andicole0]

The missing relay is the one Dax can no longer supply and is usually red, this is for the intermittant wipers. (See pic)

I'm looking for my wiring schedule for details of the additional relay (bought from Maplins), but have attached a pic of how that was connected.

HTH.

got it. I misread your diagram. The black to the relay comes out of the column switch. I'd wired seperate earths to each of the two! Works perfectly now. thanks very much for the help. Only about 25 more items to go.

I'll see if the local Ford dealer has an intermittent relay
