Re: Alltrax SR48500 Controller
The amber or orange LED indicates that the controller is seeing a full throttle signal from the cart. Check the battery pack voltage while operating at full throttle and going uphill as fast as it is possible. Report that voltage here.
A series (SR) controller will allow the stock motor to access more amperage. It does not induce more speed unless a lack of amperage was causing a slowdown like in the case where big tires caused the motor to draw more power than the older smaller controller could allow. 48 volts will induce the stock motor to make more speed and torque.
