Guys and Gals, I'm new to the form and am hoping to get some help. I've got a Honda that's kicking my rear. I was riding it and was parking it for the night so I shifted it into neutral then shut it off. The next morning fired it up and it hasn't shifted since. It will shift with the manual emergency lever but not with the ES. I've done everything by the book checking the wiring harness, changed the shift motor, angle sensor (twice just to be sure) gear position switch and even a new ECU. The display shows RN1&5 as it should but - for 2,3&4 when shifted manually. The only thing I'm questioning is, I noticed the speedometer it's working so will a speed sensor cause a no shift at all? I didn't think so since the initial Fist shift is when the quad is not in motion. If this is the case does anyone know of a way to test a speed sensor without the Honda adapter pigtails mentioned in the manual? I back probed the wires and got 9 volts with the sensor unplugged and plugged in with ignition on. When I rotate the speed sensor I get 9 volts constant where from what I've been reading should pulsate. Any help would be appreciated.
