i have a 2000 fatboy...when riding my speedo and mileage indicator quit working and my engine lite comes on...when i slow down or come to a stop everything works again and engine lite goes out...talk to harley and they said speed sensor bad..i replaced..still doing it...now im noticing when when im not riding i can throttle the bike a lil and it does it..mileage indicator goes out and engine lite comes on...let off throttle and it works fine...any suggestions would be helpful..its driving me nuts trying to figure this out...thanks
