Temp Gauge Entertainment

Good news about the temp gauge, I hope that's it sorted and your PS leak isn't a big issue.

Well after a couple of fault free weeks my gauge had a little episode tonight, a slight quiver up the way (only maybe 5-10 degrees on the scale, not full scale point to the sky!) and back down for a few mins, not terribly bad but enough to tell me the fault is still at large! Parked up (cooled a bit obviously) and when drove home later is was fine.

I'm pretty puffed out with this nonsense now, will probably just live with it and see how it behaves. My third PCB I bought has arrived, although I have managed to replicate the fault with both PCB's I already had (and kinda ruled them out), so I may swap it all over but I fear it will make no difference. The rugby balls almost certainly have a bearing on it, it could also be diode related, or both.

Dave - I'd be happy to send you this latest bare PCB board if you wanted to run some diode tests on it? (even fire in some new ones and see how it goes?) I think that might be the next step in this operation. Let me know. I am a disaster zone with a soldering iron or i'd do it myself!!

Cheers

Hi Stuart - I'd be happy to run some tests on the board, I'm not a professional electrician but I've mended a few electrical circuits now. A linear power supply on my Otari reel-to-reel machine was the most difficult. Most recently I repaired a fault on a DVD player where the 2nd laser wasn't receiving the correct voltage and reporting "no disc".

I've also just got myself a new temperature controlled iron from ali-express which comes with glowing reviews from the youtube.

I'm still waiting for the car to return currently. No doubt expensive power steering bits are coming but there can't be many places you can drop the car off at 6pm on a Bank holiday Saturday!
Which is this pcb you are talking about? I haven't changed anything out other than gauges themselves. I did try a whole cluster once but the speedo is in km so wasn't quite so easy. Actually I might have naother whole cluster somewhere. I've had that so long someon gave it to me, not so sought after then.
I'll update once it's back.

I see what you did there

Hi guys. Been busy moving house.

The PCB I'm referring to is a bare cluster, with no gauges on it, or front cover. Just the circuit board for the whole cluster.

Dave - Happy to post it to you for a play with. PM address and I'll get it sent next week at some point when I get a chance.

I see, thanks Stuart.
I'll see how I get on but I could swop out all the dials into another cluster if necessary and see how I get on.

I have done this David, and the fault persisted. I'll post this new (to me) PCB to Dave K this week for analysis!

So far the rugby balls, and gauges themselves, are the only variables that make a difference (and they obviously plug into each other), but I've a feeling that there could be a common issue we all have, PCB/diode or something related. Be interested in the PCB examination findings!

The other thing I have thought, is to try and metal polish the gauge prong holes, which would make sense, but that looks awful fiddly and nigh on impossible!

Cheers

Update on this guys is that my temp gauge settled down a couple of weeks since my last post on this, with no further fiddling as I got puffed out with it , so probably about the end of May. It's been faultless since with the car used almost daily. We will see how long this lasts. I do recall having a very long spell pre-engine rebuild without fault. Cannot remember what gauge was installed at that time though.............. The fault only started again when the cluster was disturbed during my oil pressure issues (was sender, not cluster it turned out). Maybe the set-up is sensitive to wires being plugged in and out, making a fault show, then if left for a period, seems to settle down and be fine. I can report this being true now twice for me. Possibly coincidence, who knows! [8|]

Anyway, on that note, Dave, have you had a chance to experiment on the PCB yet?

Sorry, still sitting on the sideboard, I need to print out the page from the workshop manual with the wiring diagram on. I had a quick look at the diagram a couple of weeks ago and it looked very simple from what I remember with the gauge almost wired directly to the sender with little componentry inbetween.

Will let you know what I can make out from the diagram and then if there is anything that is worth testing on the cluster [s1]

No worries and no rush. Mines is behaving just now....................
