My golf cart is weak going up hills. The battery is fine and fully charged. What should I check?

Hi, Thanks for letting me try to help you with your problem.You may have a bad controller.Here's how to check it with a volt meter.Connect (-) probe to M- terminal.Connect (+) probe to B+ terminal.Reading should indicate approx. 0 volts.Slowly depress accel. pedal. The reading should show the voltage increasing to battery voltage when fully depressed.If the voltage is at or near battery voltage and the motor is not turning, problem lies in either the forward/reverse switch, wiring or the motor.If the voltage increases by a few volts and then stops changing while the pedal is being depressed, remove the orange wire at the "Reverse Micro switch".If the voltage is not at or near battery voltage, replace the controller.If battery voltage is present, the problem lies in the reverse circuit.Re-connect the orange wire.
When you write "Connect (-) probe to M- terminal.Connect (+) probe to B+ terminal," are these the terminals ont he Controller and are they marked M and B?
