How to test controller
I have a 1990 EzoGo cart with a Curtis 275 amp controller. It has 4 large lugs and 3 spade connector terminals. Is there a way to test this controller with a volt/ohm meter?

Re: How to test controller
Welcome to bgw!
Controller output test: Hook the red probe to the B+ on the controller and the black probe to the M- on the controller. As you depress the pedal, you should read voltage across those 2 terminals of the controller. Check the power output from the controller by connecting the negative probe to the controller's M terminal and positive to the B+ terminal. Press the accelerator and watch to see if the voltage increases. It should increase from a reading of 0 to the full voltage of the battery. If the motor is not turning, the problem may be in the directional switch or motor. The controller is bad and must be replaced if there is no voltage. |

Re: How to test controller
I have a friend who has several controllers not installed. Thank you because mine is bad. Is there any way to test the controllers outside the cart? (not hooked up)
