Hey guys, bought a 97 wave venture and the display screen didnt work. Got a used screen and speedometer wont work...started it in my garage and spun the wheel in the back and nothin shows in the speed...and idea how to test it and what color wires are for the sensor.

The problem is usually with the sensor unit, and not with the display. I don't have a service manual for your ski, but I do have one for the GP760, and it doesn't show how to test the sensor. Best bet is to swap it out with a known good one.

If you want to try to test it: On other skis you apply 12v to the Black/Yellow and Red/Yellow leads then measure the voltage output between the Yellow and Black/Yellow leads when you spin the wheel. On your ski the wires may be Red/White, Yellow, and Black. You want to see pulses in the voltage as the wheel turns. Its actually sort of hard to test them without an oscilloscope, unless you have a very accurate multimeter.

well, i took the ski out and the speedo works sometimes and not others and then it may read 30 when im wide open...So im pretty sure it's the sensor itself....thanks!
