Subject: [Healeys] Fuel Gauge dampener
Hi,
I'd saved something relating to damping the fluctuations in my fuel gauge. I
don't recall if it was originally posted here or if I trawled it off the
net. I'd made a few notes and filed it appropriately against some day in the
future when I might get round to actually doing it.
So, my nephew's fuel gauge bounces around far more than mine and this
prompted me to dig out the article/notes.
First off, I agree that there's no sense in putting the capacitor anywhere
near the fuel tank.
Having said that, I read the advice that I'd stored so carefully and began
to wonder if I'd understood it correctly.
Is the capacitor really supposed to be wired across the two terminals on the
gauge? Would it have any effect? To put it crudely, but in the language that
I can understand, wouldn't the fluctuations still come down the Green/Black
wire from the sender unit and hit the gauge's terminal T? And wouldn't those
fluctuations still register as such on the gauge, totally unaffected by the
capacitor?
Shouldn't the capacitor be wired in such a fashion that the fluctuations
cannot bypass it?
Maybe I'm over complicating things and should just try it without
understanding it. Maybe I think too much.
Simon
