It means that you need a new steering wheel. -----Original Message----- From: timnagin [mailto:timnagin@xxxxxxxxxxxxxx] Sent: Wednesday, October 08, 2003 8:43 AM To: DMCForum@xxxxxxxxxxxxxxx Subject: 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. http://durman.xu.edu/delorean/pics/tach.JPG 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.

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"? :) --- In DMCForum@xxxxxxxxxxxxxxx, Martin Gutkowski <webmaster@xxxx> wrote: > That's what it does when open circuit, hence unplugging makes no difference > > cruznmd wrote: > > >2.
