Well first of all I'm really glad to hear you got the new speedo mounted up and looking good!! Nice one! But as for the problems you're having with it well... I wish I could help. Mine gave me no grief at all concerning the magnet and pickup. Once I dialed in the circumference of the wheel all was good. But your problem is just plain weird. I suppose there is a remote possibility it was faulty from the get-go. Is there a support # or a technical assistance line you can call for some help and suggestions?
