Thanks everyone. I appreciate the quick responses. New to the forum and am a little overwhelmed with all the good information.
By the way, yes it know it is the speed sensor for sure that controls signals, radio volume, and definitely not least the cruise control. The speedo just didn't quit. It starting fluctuating BIG TIME! I was kicked back relaxing with the cruise set and it went berserk! Throttle wide open, then off, then wide open, etc. Scared the crap out of me first, then when I grabbed the brake and realized what was happening I just had to laugh. I didn't realize what a wimp I have become until I had to ride the last 600 or so miles with no cruise and I can never remember to cancel my turn signal!
I guess technology ain't so bad! lol
