Can someome help me please, i'm a new rider and this is my first bike ever have, for some reason my battery died, my friend jump start me and accidently put the positive with the negitive, after that happen my speedometer doesn't work any more, but the miles reader works and the light on the speedometer work also, someone told me it's a fuse but I check the fuse box and put a new fuse in, still the same. i heard from another person there's a fuse for the speedormeter...is that true ??..    

HI; what kind of bike and year?
Most bikes have a fuse box under the seat. Along with one on the side. It may have a small fuse at the speedo head.     I would check the connections just to see that the circut did not get smoked. You will need to get an VOLT OHM meter. GOOD luck hope all you need is another fuse. DOUBBLE CHECK the fuse it may look ok but not. ...scruffy  

THANKS SCRUFFY MY BIKE IS A 2004 VICTORY VEGAS, I WILL TRY WHAT YOU SAID
