RE: [DMCForum] fuel gauge...was... Idiot light check



Ok after reading both posts, one each from Martin and Rich, I checked out
my
fuel gauge.  If you look at the picture below, the state of my car when
this
was taken was no battery, about one-quarter of a tank of fuel, a bad
sender,
the key was off, it was night time, and I was wearing sunglasses.

So, what does all of this mean?  Who is right?  I know my sender is bad
but
I haven't been into the binnacle or any other wiring yet.

Forgive me Martin, but are you sure you're right on this? Other fuel
sending units I've worked with operate like this:

As the float rises, resistance -decreases- (shorts) allowing more
power to the gauge, hence the needle rises.

As the float falls, resistance -increases- (open) reducing power to
the gauge so the needle falls.

So, as far as I understand it, I have a short, or full power to the
gauge because the needle pegs "full".

If I had an open, the needle would always read "empty".

I can see why it's confusing, because float goes up, resistance goes
down, and vice versa. It's opposite of what most people expect.

When the sender is unplugged, the power wire is shorted to one of the
other wires somewhere, still sending a full voltage to the needle
because there is no sender to put any resistance on the line and
lower the needle.

Now, how about those idiot lights? Which ones come on for test when
you put the key to "run"? :)
