Got a little niggling issue.

car is a 99 RSfourS, 100,000kms.

If i have the lights on (and thus the dash illumination lights are on) after about an hour of driving, the speedo and tacho start to read higher and higher than normal. and then a few minutes later, they completely die and the digital odometer goes out.

i have spoken to the previous owner who confirms this happened to him at night time also, so i am 100% positive it has something to do with the dash illumination lights being on, and given that it seems to always happen on or around an hour after i switch the lights on, i can only assume it is heat related??

i am attempting to remedy this by replacing all the globes with LEDs from 666DAN, but it's more of a bandaid solution than fixing the problem.

does anyone have any insight?

cheers mat

Nothing unusal going on with it?? Id rip the globes out. It may be obvious once its out it may not, go for a drive with no dash light n c wat that turns out

nah, it behaves perfectly up until that point in time.

only thing i can think that heat would affect would be causing the expansion of a connection which then loosens or something like that.

when i get in there to do the LED's ill give everything a good clean and rough up the terminals etc. hoping that the lower operating temp of the LEDs will correct the issue.

i can't seem to find anyone ever having a similar problem though, have done a bit of searching including on R34s....

Be careful of those LEDs, I bought them and had nothing but issues: flickering/strobing, burning out (so I'd lose half of my dash), etc... they just don't seem to sit in the mounts very well... I got sick of all the problems after about 6 weeks, and reverted back to normal lights...

interesting - well, i'm happy to give it a crack. i have read of a couple of people disgruntled with their LEDs from Dan, but then again, also a lot of people who they have worked well for. it's not a huge expense in the scheme of things and not permanent so i'll see how they go. and if needs by i'll investigate a way to secure them more strongly.

thanks for the heads up though.

Verry happy with my LED's from 666DAN.

Just pick the colors wisely as most dash's will have some form of filter allready in place

yeh kid,

i chose red for this reason. so i'll just try get everything in the car to red which i think will look killer. i've got LEDs lined up for the gauges, dash, cig lighter, ignition etc. i'm going to look into getting the window buttons done too.

pity the gizmo EBC is blue.....

Hi there

Im a newbee to the stagea world i have a S2 rs4s 00 stagea i also have this exact same problem i also think its heat related but dont know where to start i was thinking its some sort of resistor over heating but not sure....i also would like to know if someone has fixed this problem and how no speedo sucks on a long trip...

any help much appreciated

cheers

looks like we're in this one together, fritters!

how long does yours take to play up? and does it fix itself if you let the car cool down for a bit?

it also seems to fix itself if i turn the aircon on for a few minutes, again, confirming the heat related theory.

did a post in 'general maintenance' too. have been searching all afternoon (at work) trying to find info. even looking for posts relating to R34's but only stuff i can find mentions a similar problem with no solution - hate it when people do that!

Yeah: I believe I was one of the unlucky ones: no offence to 666Dan! Bear in mind that the LEDs are extremely bright too: I found it quite distracting when I had them installed (and working), but having since installed a number of Defi guages, I don't believe it would be a real issue, as they are quite bright themselves.... I'm more partial to a very dimmed instrument cluster...

My instruments used to play up - speedo stuck at some speed temp guage to zero fuel to max or the otherway round. Used to fix it by disconnecting and reconnecting the battery. Check earths etc. Someone suggested (witht he cluster out) waving a heat gun over all the soldered joints. Mine appear to have fixed themselves (touch wood).

cbf reading...

but have u tryed driving with lights on during the day? does this issue still occur?

yep.

will check battery earth, but nothing else is playing up - it is a very localised problem.

will also try the heatgun trick for what it's worth. its just annoying, as aside from that the car is flawless and i couldnt be happier.

yep exaxtly the same about 1 hour a little bit longer in winter....i havn't tried the a/c thing.....

starting to look that way. i've posted in another area of the forum but got only one reply which was completely unrelated.

hoping that the LEDs fix it, waiting for them to arrive, i'll keep you posted.

if not my mind has wandered as far as a 12v computer fan behind the dash haha

OK

I've had Very Similar issues in an old N13 Pulsar, Dash is sweet for a while then everything starts going crazy and dies.

Turned out the 8Volt Voltage Regulator in the instrument cluster was on the way out.

It's used as a reference for all the guages, so when the output wanders all the guages are affected.

simply soldered a new "7808" from Dick 'head' Smith and bingo, we had speedo,tacho,temp the lot.

There things are temp sensitive so the heat of the lights seems to be the last straw.

Hope this helps someone

Cheers

well that might be the case but i managed to fix mine just be replacing all the globes with LEDs.

hasn't played up once since - so it is obviously heat related as the LEDs run a lot cooler.

i had a look at the back of the dash and someone has soldered an extra wire onto one of the copper tracks for the alarm. maybe to pick up the 'door open' signal - i dont know, seems dodgy. i think that might have had something to do with the issues - the heat affects the delicate plastic sheet that the copper tracks run in, then allows it to flex and move and touch other pins or something. who knows. LEDs fixed it......just got to put up with replacing dead LEDs every now and then....

    • Yep, I like that. The tags are only on the first post of a thread and we don't get huge numbers of new threads. Also, I plan to add some more report types and we could have a member report type like 'review tags' then members could flag if they thought a topic wasn't tagged correctly.  No way man, I dig the input. Thanks! 
    • It's a valid thought. There's not exactly that functionality already (when creating a thread) - that's where the OP can use/create any tag they want. We'd have to come up with a way for the user to request their tags get reviewed or something. Otherwise the mods would have to review every new post's tags (for those that have them, anyway). There's kind of that functionality already exists to some extent, post facto of starting the thread, where the OP or any other user could report the post to admins, and request that tags get reviewed. We could do this already, and any user could already have made such a request. To make it a part of the forum proper, it would require an initial and an ongoing education programme, so that people know that it's a thing. OP based tagging/request for review would also require at least some (probably most) of the user base to be told that it's a thing they can do. Both of these things probably wouldn't spread too far and/or get used very much. If it was the standard approach on a lot of different sites, then it might do, because people would be used to it. Prank's approach to this differs from my original thought, by leaning into tagging. Which is fine - it's possibly better than what I originally suggested. In fact, I just went to the R32 GTR wiring diagram thread and added tags, including "Library". That's probably a good way to use tags and the idea of a library. We just have to drag together an (organised!) index of threads or posts that have that tag. I have yet to do any of my own follow up by pursuing worthy threads and posts and reporting/marking/tagging them for the library, such as the @Sydneykid stuff I was talking about, and possibly any amount of @Lithium 's and others' posts. At least if I tag them Library, we'll have a start.   Back to @Wazmond's idea as it relates to @PranK's, we might have some sort of a list of tags that are already used to scrape for this library. I'm not entirely sure how that would be presented or used, particularly if it got long. But it's yet another idea!   cheers
    • Just a thought, but instead of restricting, is it possible to do like an "up for review" kind of thing? Where say someone who's not an admin/mod tags, it would require approval for it to actually tag? User posts with a 'tag' > Admin/Mod Reviews > Approves tag > Tag now exists kinda thing? Just came across this thread so Im not too sure if Im straying off topic or not but forgive me if i am...
    • Yes, a plan for non-action is always my first sort of plan! I'm happy to see what falls out of invision's update. I had been having some thoughts on what to do with this the other day and they all seem to have fled my memory, after various solar panel induced traumas, squeaking suspension sphericals, etc etc, over the last little bit. I'll try and recall what I had in mind and make sure that I put it into print in some form before the Alzheimer's strikes again.
    • The ability to have both a 5500 stall for launching, and a regular lockup for every other scenario is pretty sweet. Does it actually work well like that though in the real world? Would it hold up to track use and otherwise you'd never know you had a stall converter in it? If so, that's awesome
