Please help!
I have a 04' Rancher TRX350 ES 4x4. The miles on the speedometer showed 160 miles, but after the battery was replaced the Display changed from mph to km/h and it raised my overall hours to something like 450,000...which is equal to over 5 years of straight riding, impossible for an 04. It is not the trip reading 450,000 hours but it's the overall engine hours and km that are all messed up. I've already attempted to unplug the display, battery, and fuses..but it did not help.

Does anyone know how to perform a master reset on the display? I'm not trying to get it back to 0, I'm just trying to get the display to show the actual hours and miles. If it's the only way to fix it than I will.

I need:
1) it to change from km/h -> mph
2) show actual miles & hours

Any suggestions would be greatly appreciated.
