Been following this thread, some useful info. I've also bought a new voltage regular to try and remedy my fuel guage issue. Sent from my Pixel 3 XL using Tapatalk
So I'm guessing that both types of stabiliser work the same until they reach the end of their working lives. The more modern zener diode type dies in fail safe mode, but the vibrator may take out the gauge?
I would expect the modern one to fail in safe mode yes, they don’t work the same way as one is electronic and one is mechanical, but the produce the same output
I wouldn't bet on it, depends what's inside, if the regulator is based on a monolithic IC chip, they often fail short circuit, tho I guess it does depend on the failure mode.
Volt Reg arrived, see pic. The output is 5.65v .... close enough to 6v I assume? Bad news - gauge does nothing, even when I earthed the gauge's "sender" tab, nothing. No movement. Zilch. Anyone got a fuel gauge they don't want?
...can I use an earlier fuel gauge? Looks like places sell them to the 73 model year, but mine is 79.
Later ones are like rocking horse s***. Not sure if yo can get an early one to fit. Instrument clusters often come up on ebay but fetch a good price particularly later ones.
yeah, my thinking exactly. I reckon the part-id on their advert is wrong. haven't actually taken mine out, so will do that, and compare what they look like.
After following this thread, and ruling out the fuel sender which is new and the wiring showing correct ohms, im hopefully i've fixed my fuel gauge issue by replacing the regulator. Bought from here: https://www.ebay.co.uk/itm/Car-FUEL...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649 as i refused to pay the near £30 just kampers wanted for what looks liked the exact same product.
That's the one I bought too! Unfortunately, I broke my gauge as you know, so that's on the way. I currently have a multi meter attached to my wiring so I know the fuel level from the number of ohms resistance . I also plotted a graph of ohms vs fuel level (it's not a straight line) and created a calculator in excel to show what the fuel gauge should read.....perhaps I'm overthinking all this 1979 Super Viking, 2lt type 4, Automatic
