I bought a beautiful 99 last year and love it. However, I cannot figure out what is the problem with my speedometer/odometer. The sprocket nut is tight, I have tried 2 different sensors, but nothing. The cluster connector cleaned and plugged back in and still zip. Measuring voltage at the b/r wire I get 1.8v, and the pink signal wire 4.5v. I get no variance when turning the back wheel. Any ideas? I am curious to know what the b/r supply voltage should be?
