Blowing Fuse - Any Ideas

[Shadlar]

I have a 2006 Outlander 800 that is blowing the 7.5amp fuse labeled ( F4 - "Accessories" in the shop manual ) - (F4 - "Speedometer/Speed sensor/Tail lamp" in the owners manual) every time I try to start it. Has anyone seen this before, and what was the solution? I only have 2 weeks vacation this summer starting on Aug. 10th and would really like to have my quad running. As a side note the last time I rode the quad it worked fine, but the speedometer did not work. ( all lights and indicators worked, digital display worked. Everything but the speedo needle.

I'd start with checking continuity on your speedo wire(s). Could just be a bad ground wire.

if its blowing a fuse it would have to be shorting out.... a bad ground won't make it blow... but if its crossed to ground then yes could blow it

What we found was that the vehicle speed sensor was bad. We unplugged it, put in a new fuse and it fired right up.

so the sensor was shorted then

The quad is at the dealer right now. We think that's what it is but will know for sure in a couple of days. All I know is that as soon as we unplugged the sensor it worked fine and did not blow any fuses.

Usually yiou can just clean the speed sensor and the problem is fixed. Changing your trans oil more often will make the problem go away....

Just a quick update. My wife took it in, they changed the speed sensor. I picked it up and went camping for my 2 weeks holidays and the quad performed flawlessly the whole time. I kept the old sensor and will try cleaning it and reusing it ( As suggested by DaveB ) when i have more time.
