I have a 95 H1. The speedometer has quite working until I apply the brake and slow down to about 20mph. Thats when the needle will come up and work until I stop. If I try to accellerate the needle goes back to zero. I have taken the speed sensor out from the tcase and cleanthe sensor. No fix. I've put in the OME spacer and still not working. I have replaced the sensor and still the same problem. The ohms reading is 1.4 on both sensors. Any one have any ideas? Where does the wires from the sensor go to and from there does it go to the speedometer? Thanks

 

Mine did that and needed a new neutral safety switch.
