any of you clods have problems with your out of fuel idiot light? mine has never come on and i've run right dry out of petrol several times. the light comes on after the circuit the sender goes "closed" for a couple seconds, then the light flashes and the odo flips to the "f" position. i can make this happen if i jump the terminals at the sender. just popped the sender itself out right now and i cant get it to go "closed". shake it, scream at it, drown it in petrol, etc, etc... it aint going closed. y'all think i need a new one? is it just a little float, or is there more in there than i can see?
