Mk1GLS 0 Posted June 12, 2004 Hi all, had a problem recently - with my wiring. It appears a couple of other have had the same issue after doing a search! The feed to the light switch light burnt out down the middle of my wiring loom. The effect of this was as soon as I turned the ignition on the lights came on - very volvo -esque! However I fished the wire out & disconnected it & only seem to have lost the light to the switch which is cool... Anyhow after putting it all back together my rear spoiler didn't work automatically. I have been back in it & had the 'rats nest' out again - but canna find the problem. It still works manually. I assume I have knocked something somewhere in there. Can't find any knacked fuses (although I dunno where it is fused anyhow) and checked all the wiring I can see on the control box. How does it sense the speed for going up & down? I feel this may be the issue - I heard mumblings from another source of something behind the speedo for this - but cant find anything. Any thoughts? appreciated.

Bobbywhacker 0 Posted June 14, 2004 I have exactly this problem.... so frustrating isn't it Quote Share this post Link to post Share on other sites
Mk1GLS 0 Posted June 14, 2004 Yup! :( I have read thru all the various topics in the forum covering this & no-one REALLY answers mentions of a wire behind the stereo (this wasn't touched when it stopped) and also the speed sensor on the back of the dash. But no mention of what this sensor looks like or where it is. Someone must know??????? :mrgreen: Cheers oh - my other cars are a mk1 GLS in bits a mk11 GTS in bits & a beige escort diesel van!

Bobbywhacker 0 Posted June 14, 2004 ok, well here's what I've discovered so far... The controller lives above the fuse box, behind the dash, to the right of the steering wheel (RHD), black box about the size of a tobacco tin (old skool).. The manual switch feeds directly into this.. blue/white wire up vertical lift, green/white for spoiler descent and a brown negative/earth. Then there are green and yellow wires that run from the controller to the rear spoiler.. these change colour towards the rear of the car. There is a white/blue wire that runs to the stereo.. apparently this is the one that causes a lot of problems, but not in my instance because i cut it off and still no joy. Finally there is a another brown wire (negative/earth) that commons up with the other brown wire and a seperate black/blue wire.... this is the one that is I guess causing our problems!! I know it goes direct to the fusebox on my '94 VR, as does one of the earth/negative wires. I get a constant 13volts across this wire.. its the only one that would seem to control the controller, if that makes sense, but I can't work out, and no one else would seem to know, precisely what this wire does when it gets the fusebox. If you do have any joy, can you let me know!!! :( Quote Share this post Link to post Share on other sites
Mk1GLS 0 Posted June 14, 2004 pretty much where I was! The only thing you haven't mentioned and is mentioned on the forum is the speed sensor which is somewhere on the bacl okf the instrument cluster? Dunno what this looks like or if is is a seperate bit or part of the cluster. the only bit of info I have uip to now was in an e-mail that went as follows: ""Apparently it is probably caused by a loose connection under the dashboard. The connection is not on the speedo but an inline connection block round in shape."" ?? :?: cheers Quote Share this post Link to post Share on other sites
Bobbywhacker 0 Posted June 14, 2004 hmmmm.. I've had the instruments out.. to be honest all I could spot were a bunch of white wires, don't recall seeing anything else obvious.... I was lead to believe the speed lives on the fusebox.. but if it were faulty, then the speedo wouldn't work either!!! Its so confusing and annoying!

Mk1GLS 0 Posted June 14, 2004 hmm. the problem happened to me when I removed the shelf and the fusebox slighlty to sort some wiring out. It stopped then. I then went back in fiddled about & it started - yeah hey. Only for it to stop again the next day. Boo. So I must disturbed something ddown there. SOMONE MUST Know? All we need to know is what we are lookingfor here. Hep anyone???????????????? :( will have another dig wednesday. cheers Quote Share this post Link to post Share on other sites
Bobbywhacker 0 Posted June 14, 2004 a photo would do!!... I've got tonnes of lose wires in the fusebox, but I dunno if they were for options that the car hasn't got Quote Share this post Link to post Share on other sites
stevemac 0 Posted June 14, 2004 U guys want wiring diagrams ?? Quote Share this post Link to post Share on other sites
Bobbywhacker 0 Posted June 14, 2004 Yeah, that'd be really helpful and much appreciated Quote Share this post Link to post Share on other sites
stevemac 0 Posted June 14, 2004 Here's 1 for a US spec VR6 (2.8 AAA engine) - don't have any diagrams for the 2.9 UK spec version Quote Share this post Link to post Share on other sites
Bobbywhacker 0 Posted June 15, 2004 Cheers for that... the US spec seems the same as Euro.... If you follow the blue/black wire from the spoiler controller, it says at the end T1g, T1h etc.. what does this mean? Quote Share this post Link to post Share on other sites
Mk1GLS 0 Posted June 15, 2004 wires loose - yup loads! Lots of ends. & little blocks with nothing coming out - a real rats nest. Will have a look at the digrames & digest - but bearing in mind it appears I occasionaly have spelling probs - dunno how much succes I'll have ;-) cheers Quote Share this post Link to post Share on other sites
stevemac 0 Posted June 15, 2004 it says at the end T1g, T1h etc.. what does this mean? Not sure but I've altered the title of this thread to maybe get a few answers :wink: Quote Share this post Link to post Share on other sites
stevemac 0 Posted June 15, 2004 Mk1GLS, Mike, I've just realised who you are - did you get your running problems & chip sorted ?? I've moved from Leeds to Birmingham since we last spoke. Welcome to the forum m8 8) Quote Share this post Link to post Share on other sites
Bobbywhacker 0 Posted June 15, 2004 RIght, just taken the cluster out again...... erm, all I have in there are the clump of white wires (and a few colours) going into that fat multiplug.. should there not be some kinda speedo cable?? Or this vacuum pipe I hear so much about??!?! ...... my speedo does work.. dunno how accurately..... Its a '94 VR6 btw Quote Share this post Link to post Share on other sites
Mk1GLS 0 Posted June 15, 2004 ah yes - Just noticed me self! Dunno really - certainly got it running better over time with tinkering. No Doubt. But having never driven another G60 can't compare... All I know is that I occasionally think - hmm it's not so fast is it? Until I look at the speedo or the corner I am approaching appears to be coming up rather fast & then think - hmm mebbe it is then! You have to remember I am a Scirocco freak - always have been - especially Mk1's, so very seat of the pants non modern driving. Not quite so rmoved from the speed you are doing as in a Corrado. Never touched or went into the chip side of things. Dont even know if the chip that is supposed to be in is - I have built loads od roccos's but they dont have things like chips - so dont mess with what you dont know! Unfortunately though gonna have to sell. I have a Mk1 GLS in bits with a 16v engine & 45's waiting to go in it. A GTS wating to be played with and no time. While I have the G60 I am not gonna find the inclination either. If I am having to use me old Escort Diesel van then I may make the time ;-) bit of a quick chnage of subject but what are they worth currently? I paid £2400 I believe just b4 I last spoke to you. Must say though this spoiler thngy is getting up me tits! Birmigham eh. The home of japser Carrott. You'l be in the minority race down there then. Or is that a racist - small minded yourkshire thing to say. sorry! :oops: Quote Share this post Link to post Share on other sites
stevemac 0 Posted June 15, 2004 should there not be some kinda speedo cable?? No cable - fully electronic speedo Or this vacuum pipe I hear so much about??!?!Vacuum pipe is not present on VR6 models Birmigham eh. The home of japser Carrott. You'll be in the minority race down there then. :lol: :lol: bit of a quick chnage of subject but what are they worth currently? I paid £2400 I believe just b4 I last spoke to you.Depends totally on condition, mileage, service history, etc. As a guide G60's usually fetch between £2000 - £4000. Maybe as much as £5000 for a perfect, extremely low mileage car. Quote Share this post Link to post Share on other sites

I feel this may be the issue - I heard mumblings from another source of something behind the speedo for this - but cant find anything. Any thoughts? appreciated. There is a speed sensor behind the dash - I'll try to find a diagram for you :wink: There is also a resistor in the spoiler mech or control unit (can't remember which), the rating of this resistor sets the road speed at which the spoiler rises.
