Default Re: Speedometer problem from RFI or EMI.

Thanks for clearing that up (I'm a newbie when it comes to these motors). I agree that a better plug wire and boot can make a difference. However, a ferrite bead will block RFI and EMI from entering the electronic device along external wires, which act like antennas. Try it, it may fix your intermittent problem.
