I have a Sevcon gen 4 80v/350a controller . part number #634A83310 . Some freinds(car guy's) are holding some Leaf motors for me . I want to order a wiring harness from thunderstruck , but I do not have the encoder to resolver thing figured out . I will pay some one to and or order and set up my controller to the leaf motor . The Sevcon will need to be programed to work . Or if the controller can be made to work with no controller encoder , I am fine with that . Yes , I will pay for shipping both ways and for parts . And yes , I will pay you too . P.M me if you can make it work . I was told $650.00 to repair the DC motor . If I could spend that to get the Sevcon an Leaf motor working ...I would be happy to do that . And yes , I will be using another Leaf motor an controller on the car later . They can not hold the motors for me for ever so let me know soon . Or I will just sell the Sevcon and stay DC .
