So the speed sensor was def faulty new one fitted today and now pump motor ramps up to full speed with no faults, traction is fine, but combine the two and it still throws up T312 or L286 at probably 3/4 to full pump speed. iv checked all connections large and small wires, slight corrosion on the pos battery take off, replaced it anyway. The truck has gone through a complete charge cycle and all cells are at 2.11/2.12 standing charge battery at 50.92v so close yet so far, there is another truck of the same model/spec so i will try switching batteries but dont think ill find an answer, any ideas guys?
