Instrument Cluster solved..at last!

At long last I have my speedo,tacho, odometer, temp and fuel gauges finally working as one.
Twelve months ago I did the extra earth cabling thing after a very long period of non functioning dash and $500 expediture but all was not resolved until a final clean up of the positive battery terminals (dual) at that time.

Then it all started all over again, I reckoned around Sept. at about the same time I had a Diesel/Gas conversion. Up until last week the cluster would start up okay and last about 20 mins a day on average before complete failure.

After a lot of research on this site, I finally found a comment from someone, bless his sole and I sincerely apologise for not noting who it was but I found a reference to the fitting of spot lights on a bull bar and how not only should the lights be earthed to the bar but the bar should also be earthed to the chassis.

So I thought I would try this analogy and decided to run an EXTRA earth from the diesel gas earth on the body to the chassis...and BLOODY HELL..IT FIXED IT.
I have now done about 500kms and 8 days of uninterrupted Cluster bliss.
So whoever you are, my sincere thanks and thanks also to everyone who offered their support in my recent posts.
If anyone experiences anything similar after fitting any electrical accessory do yourself a favour and run an extra earth from that point to the chassis.
In my case it was only a small piece of 4mm ,10 amp cable that did the job.

Always good to hear a happy ending...:)
Had a problem with four dash warning lights flashing intermittently and used this forum to try to solve the problem. Improved the earthing and all that did was to make the lights flash more brightly. So I now have better earthing. Also pulled, checked, cleaned and replace every fuse and relay that I could find but no change due to this. In desparation called Guest 4WD and was advised that it would probably be a low voltage problem and to check the alternator. The alternator had in fact been replaced only a few months beforehand. The happy end is that, by pulling the plug from the alternator and spraying the contacts with contact cleaner the problem was solved and so far hasn't returned. Thanks for a great forum.
posted 2008 and here we are 2023. i havent tried this but i will, having the same issue. this definitely makes sense to me. after adding leds in my cluster, it stopped working as a whole and the fuse for my headlights and spotties blew.

thank u good sir

Did you put the LED's in the cluster the right way round? Remember they are a 'light emitting DIODE' so current will only pass through in one direction.

If the fuse for headlights and spotlights have blown, then it also sounds like an earth leakage, short circuit somewhere. The spotlights will usually share a positive wire from the headlights high beam, to trigger the spotlights only on high beam. So pull the plug off the back of each headlight and inspect for signs of a short circuit, burnt plug etc. It's very common to melt the earth wire because if you run high wattage globes it overloads the earth wire, or when use the high beam flash function on the indicator/headlight stalk for too long it lights up both of the high and low beam filaments at the same time so melting the single earth wire and possibly causing a short circuit somewhere.

i bought some t5 stedi leds, theres no polarity on them, they can go either way

i will try this weekend or run another earth like @Porks did, hopefully it puts my cluster back to normal
