    1300r help

    I just got a 1300r and the fuel gauge is acting up. Most of the time it just stays on 2 bars. But the other day it went to full and worked fine half the day. Can anyone tell me where to start and what to test? I would like to get it fixed b4 the weeken

    Never messed with the one on my ski, but they all pretty much work the same.

    You have a variable resistor inside the tank, attached to a float. When the float moves up the resistance changes, depending on how it's designed, the resistance will go up or down.

    In my experience, the higher the float goes, the resistance goes down, eventually resulting in a complete short.

    I'd start by unplugging your sending unit on your tank, attaching an ohm meter and moving the float by hand. If you don't get a smooth and consistant ohm reading while moving the float, replace the sending unit.

    Thanks man, I'll go out and ohm it out with a full tank and see what it reads.

    A single test at a fixed point wont really help.

    What you need to do is watch what the sending unit is doing over the entire range of motion.

    Most of the time when these things go bad, it's either due to a stuck or punctured float, or the contact surface of the sending unit has been worn through. Both of which require removal of the sending unit from the tank for proper diagnosis.

    probably a bad gauge sender in the tank... its on the side of the fuel module

    they are not available seperately, but I have a few good used ones

    I pulled everything out of the tank. When it should be full it reads around 138 ohms and empty was around 0. The switch doesn't look too worn either.

    move it slowly top to bottom and watch for dead spots on your meter

    also look for slop in the arm

    the in and out movement can cause the arm to pull away from the resistor

    if I remember there is a metal nut that holds the arm in the pivot

    see if you can tighten it up a smidge, but be careful, it is very fragile
