The motor brushes and bearing were bad and the brushes were "cleaned up" and the bearing replaced. Could this damage in the motor helped to cause the controller go out.
Again, if I tested correctly, the controller ha 27 V initially and ramped up to 37 and then back down to 27 as I pressed the accelerator.
I think I will just buy the motor and controller and be done with them.
My cart is lifted with large tires and has the back seat. Only 2 people ever on it maybe a few bags of garden mulch on the back seat sometimes and flat terrain in my yard. The original motor worked fine for years. Do I need to upgrade the motor and controller based on my cart's configuration to not over stress the motor / controller or would stock replacements be sufficient in your opinion? Trying to not spend more than needed right now but will spend what I have to.
Thanks for all of you help, I really appreciate it.
