    low fuel guage with tank full?

    I was wondering if any one knows if there is a common problem with the fuel guage not working. The ski got low on fuel. I filled the tank and the guage is still showing empty. I pulled the sender and turned it upside down and the guage is still showing empty. I checked the sender with my volt meter and it only read from .003 to .019 from the float being at the top all the way to the bottom. That doesn't seem right to me but this is the first ski I have ever worked on. Any advice will help.
    Thanks in advance.

    Welcome to the Hulk

    Click here for the Polaris Service manuals.

    What year and model is your Polaris?

    The sender is checked using the OHMS setting on your meter, when unplugged from the ski. 33 ohms is full tank, 240 ohms is empty tank.

    Welcome to the Hulk.

    More than likely the float is gas logged and sunk if you have the new style.

    If you have the old style, I bet the wires came loose.

    K447 is correct. Test with an ohmeter and 33 ohm (full) 240 (empty)

    I pulled the sender out and flipped it upside down while the wires were connected and the guage still showed empty.

    Disconnect the two wires and put a 33 ohm resistor across the two wires and if it shows full then you have a pretty good idea that the problem is the float. I ran mine that way for 2 months just made sure I had fuel in it so not to run out.

    I believe a 96 slx has a captive float sending unit (long silver tube). Flipping it 180 degrees will cause the sender to bypass the last contact on the PCB and have the same effect as no float at all. Tilt it horizontally and give it a little shake so the float is near the middle of the tube, what does it read now? If you get a reading between E and F on the MFD or 33 and 240 on a DVM then the float is bad. Take it out by removing the black cap at the bottom and drop it in a cup of gas, if it sinks order a new one from Randy at Watcon. If you get no reading then the problem is either in the PCB or the wiring coming from it.

    your right about it being the long tube with the float in the center. I appreciate all yals input and if I can ever get home from work at a decent hour I'll see what the guage shows by sliding the float up a little.

    Ahh i just stuck a 33 ohm in the line perminantly. Now it always reads full, I usually just life the seat off every couple hours to check the fuel level.
