Well as I was out testing the new grips I installed today, I noticed that me Speedometer was not working, and the turn signals were not cancelling. I checked the Speedsensor for any metallic debris that might have kept it from working properly, but it was pretty clean. I am going to check it for trouble codes in the morning and was just curious if there is anything else I should check to be sure it's the sensor? Is there a way to check it with voltage to know if the sensor is good or bad? Are these sensors known to go bad? I don't want to buy a new sensor and find out it is something else.
