Six months ago in Colorado similar symptoms on a identical motor, upon opening the motor all sorts of water poured out and all sorts of corrosion were in evidence. But not this time. However it still seems that the problem must be magnets, epoxy tint place around the inside of this metal rim, have come loose. But there are further risks in removing centerpiece with all the copper wire so I am hoping to hear from the factory before proceeding. If the motor is even the problem, which seems 99% likely, then what to do? One, repair it if possible. Under $100 and many many many hours of Labor? 2, replace it with a like motor if that can be secured, $900. Replace it with the proper solution which is two additional Motors one each in the front wheels of the trike. 3, $2,000, but then this vehicle, James home for as many years as he can proceed, is the vehicle it should have been all along.
