Check Your Balls!

Your rugby balls that is.

I found I have a couple of niggles, this weekend is the first time I have actually filled the fuel tank to the brim only to find the my fuel gauge only reads 3/4 full. I had also noticed over the last couple of weeks my voltmeter had dropped to just above 12v and fluctuating. After googling my fuel gauge issue I tried this little tip of removing the instrument cluster and cleaning what are described as the rugby balls, there's four in total and in the picture below you can see I have removed one.

To remove the rugby balls undo the 7mm nut and carefully use a flat blade screwdriver to lever them up, once out clean the brass pins. The post I read says to clean them with metal polish but I used some micro mesh ( which is really fine wet and dry) you can see the difference :shock:

I cleaned all four of these up and also cleaned the legs on the removable resistor which straddles the voltmeter plus I took the opportunity to fit led bulbs to the cluster and one that lights the window vent symbol, another plus was until today I had never actually bothered to figure out where the trip meter reset was but when I found the switch was adrift behind the vents I now have a working trip meter also.

So after a few hours fettling I now have a fuel gauge that reads full, a voltmeter that reads approx 13.8v and is steady (the best its ever been), led illumination, and a working trip meter and a big grin :D

great write up and guess what I'm going to be doing on a rainy Bank Holiday MOnday !

BTW where did you source the LED bulb replacements from ?

did your clean up process as documented - great difference to both the Fuel level (now showing full as opposed to 3/4) and the voltmeter, haven't had chance to see the difference on temp gauge yet.

With regard to the LED's did you just get matching amp/configuration for the bulbs ?

Brilliant - I have long thought that a couple of mine seemed to read low on the gauges, and thought it might be an errant voltage regulator - this matches with what I had guessed exactly! All I need now is time!

 
I have seen a great difference on everything but the oil pressure gauge, I have just driven 250 miles and all is well.

The let's well to be honest I have had them so long I cannot remember what they are but I would have bought them on someone else's recommendation.
