pinky Posted December 15, 2020 Report Posted December 15, 2020 Hi, I have got caught out with the fuel gauge a couple of times, When empty the gauge is showing 1/4 full, when full it takes a long to time for the gauge to start falling, The tank is empty, so I moved the float with a hook, this seems to work OK, can you adjust the float in situ i belive the float needs to be pulled up slightly to allow the arm to fall down further Or does it need replacing , it isn't the voltage regulator as it has been replaced, Thank you , (stay save) pink Quote
ntc Posted December 15, 2020 Report Posted December 15, 2020 If any of the above has been changed they need to be calibrated to be accurate. Quote
jerrytr5 Posted December 15, 2020 Report Posted December 15, 2020 How do you calibrate them Neil? I didn't know you could do that. Jerry Quote
DaveN Posted December 15, 2020 Report Posted December 15, 2020 (edited) On the back of the gauge is two little adjusters, they may be hidden behind cork plugs. Pull the gauge out and reconnect it. Empty the fuel tank. Switch on the ignition Watch where the gauge settles to. Adjust the adjuster with a small electrical screwdriver until it reads Zero Use something like a length of metal coat hangar wire suitably bent lift the float up fully. Adjust the other adjuster until the tank reads full. Check the empty position again. Stick it all back together.... job done! As you look at the back of the gauge the low level adjuster will be the r/h one. Due to the hysteresis of the gauge and sender you may have to do it several times. I have mine adjusted so there is still a gallon or so when the gauge reads empty. Edited December 15, 2020 by DaveN Addition Quote
pinky Posted December 15, 2020 Author Report Posted December 15, 2020 Top man dave Well what a cracking bit of information going to have to try that Cheers pink Quote
Waldi Posted December 16, 2020 Report Posted December 16, 2020 Hi Dave, You get a rhumbs up from me too:) Waldi Quote
jerrytr5 Posted December 16, 2020 Report Posted December 16, 2020 Well I never. Can we get this saved as a 'sticky' please Mr Moderator ? Jerry Quote
cp25616 Posted December 17, 2020 Report Posted December 17, 2020 Have to say Dave that's a cracking piece of information to share, I certainly did not know all that (or part of it actually) until now, many thanks. Alan G Quote
John Morrison Posted December 17, 2020 Report Posted December 17, 2020 Hi all, have changed the title a tad, to flag the the calibration info, and have 'Pinned' topic as requested for the future. Can I ask, does this only apply to TR6 guages, as the info is, at the moment pinned in our TR6 section, or apply to other TR Fuel Guages also, in which case it perhaps should be moved to general technical - only asking? John. Quote
pinky Posted December 17, 2020 Author Report Posted December 17, 2020 I have an old fuel gauge and been having a play with it, i found the 2 holes in in the back of the gauge, The slots are in the iner frame of the gauge,so as you twist the driver it moves the frame, it is very hit and miss Definitely want to put some lube in the hole, trying to get it between the plates, very small amount as it could mess up the inside Pink Quote
AarhusTr6 Posted December 17, 2020 Report Posted December 17, 2020 I would give this a Trophy or a Like if the function was still there DaveN ;-) Quote
Mike C Posted December 18, 2020 Report Posted December 18, 2020 Inspired by this thread, I've just had a look at my fuel gauge. With the ignition on but the engine not running it oscillates fairly quickly between over 3/4 full to just under 1/2. Would this be a voltage stabilizer problem ,or maybe , as I had the dash out last year- a loose connection somewhere? Thanks for any advice. Quote

Now I can throw away the 1/2" dowel dip stick. Quote

Used same on aircraft for many years. Always more accurate than Cessna gauges. For the 6, I just know that it underreads by 1/4. Edited January 28, 2021 by stallie Quote
JohnC Posted January 29, 2021 Report Posted January 29, 2021 (edited) My rear view mirror vibrates too much to read the graduations on the dowel when I'm driving. Edited January 29, 2021 by JohnC Quote
tim hunt Posted January 29, 2021 Report Posted January 29, 2021 John, I suggest you remove the mirror from the windscreen frame and refit it with a rubber gasket, I made one many moons ago from a piece of old inner tube and this completely solved the problem you describe, which similarly affected my mirror. Just a thin piece of compliant rubber is sufficient to isolate the mirror from body vibrations. Tim Quote
JohnC Posted January 30, 2021 Report Posted January 30, 2021 Thanks Tim! Now I'll be able to see the dowel floating up and down as I'm driving But seriously - good tip. Quote
CP26309 Posted March 16, 2021 Report Posted March 16, 2021 You mean I can now throw away my dip-stick! Quote
