Gauges And Dials All Over The Pace!

[changingman 7 1 Cars]

Hi there , I've just picked up a 1.9 205 gti with a gti6 lump and mi16 box with lsd and all the clocks and dials either don't work or read wrong , except the fuel gauge!!!!!

Mechanically the car feels spot on and the gears feel nice and tight,haven't given it the customary thrashing yet , but I will!!

I bought it for a track car but it's pretty straight and tidy so I'm going to tax it etc and use it on the road at weekends which is why I need all the dials etc working.

Has anyone else experienced these sort of issues? ?

 

Cheers

Liam

Which gauges do what exactly?

 

No reason why all the gauges shouldn't work exactly as intended following a GTi-6 conversion, but plenty of conversions are somewhat dubious electrically shall we say.

Hi , the minute I start it , the stop light comes on immediately. , the oil pressure goes immediately to max, water temp goes immediately to as high as it can go, speedo doesn't work neither does the Rev counter, I knew about it before I bought it so I don't feel cheated In any way.

It's apparently an ex rally car with an MSA logbook.

It starts first turn of the key with no throttle whatsoever and ticks over like a dream.

No oil or water leaks and the gearbox is nice and tight.

The box is an mi16 with lsd and this is apparently why the Rev counter doesn't work.

 

I know I can get aftermarket guages but I'd rather the originals worked.

 

Maybe it should go to an auto electrician for a health check.

 

I've no reason to doubt that it's not what the bloke said and the recent rebuild didn't occur as everything else is spot on , just the crazy gauges

Speedo is cable driven in exactly the same way as the original 205 - only slight difference is with a GTi-6 conversion you ideally want a slightly longer cable to give more clearance on the exhaust manifold (I use a 405 cable). If this doesn't work, check that the cable is connected at both ends and that it's not snapped internally. No electrics involved on a 205 speedo.

 

Rev counter won't have anything at all to do with the gearbox. It's probably not been wired in - either needs the rev counter modified so that it can be driven by the GTi-6 ECU, or you need to run a tacho converter (basically a series of diodes) to drive the rev counter from the four GTi-6 coils.

 

Other gauges and lights just sound like they've not been wired up correctly and/or possibly don't have the correct senders fitted - all but the earliest (Ph1) GTi-6 engines don't have an oil pressure gauge sender fitted as standard. Again, easily enough resolved, depending on exactly how hacked about the loom is.

 

I don't think a typical auto electrician is what you want for a job like this, but rather someone who knows what they're doing with 205's and has experience of engine conversions (and more to the point, wiring them in properly).

 

You absolutely do not need aftermarket gauges as the originals are easy to get working - the only question is normally how much of a mess of the wiring whoever did the conversion has made and how easy that is to subsequently rectify.

 

If you were closer I'd offer to take a look for you, but I'm not sure when I'm next going to be up Buckinghamshire way. There are guides on here for wiring up GTi-6 conversions, but it doesn't sound like you're particularly electrically minded and thus tallying that with what you'll find when you delve into your might prove a challenge.

Hahaha hahaha haha I am not particular anything minded, I just get in and press the loud pedal!!

 

Thanks though, you've given m a fair bit of info , I'll have a good read of it later on and plan my attack!!

Thanks Anthony!

Stop light, oil pressure & water temp issues could be an earth where there isn't supposed to be one of the multiplugs on the back of the clocks ...

 

The list I have to hand of the connections is below if it helps :

 

Looking at back of pod, numbered L to R

10 Way

1 Oil temp light - see 10 Way 3

2 Oil pressure gauge

3 Oil temp light

4 Water temp light – see 7 Way 2

5 All 4 gauges – earth ?

6 Water temp gauge

7 Oil temp gauge

8 Water temp light ?

9 Oil temp light - see 10 Way 3

10 Back of rev counter – not used ?

 

9 Way

1 Not used

2 Not used

3 Rev counter ?

4 Rev counter ?

5 Choke light

6 Not used

7 Not used

8 Earth ? - see 7 Way 4 & 8 Way 8

9 Right indicator light

 

7 Way

1 Battery warning light

2 Stop light – see 10 Way 4

3 Brake warning light

4 Earth ? - see 9 Way 8 & 8 Way 8

5 Left indicator light

Excellent, thanks, it may come in handy as I'm. gonna try and sort as much of it out as I can! !!
