Power issues

[sirbrez]

Here's the issues, 2001 club car ds, speed motor, 4 gage cables, heavy duty f/r. Had issues moving at all and the controller smelled burnt. Replaced that with a new 500 amp controller and the solenoid was not working and when tested was not doing anything so that was replaced. Still nothing. No clicking of the solenoid or anything. Thought mcor was next. It had been previously upgraded to an Mcor 3. Installed a new one. Now we have movement however... It has full power under about half pedal. And it cuts off after pedal is pressed over half. There is no slow roll to it. it's balls to the wall or nothing. Mcor only goes in one way but it seems to me like it's 180 off or something. By the way the controller and everything that was replaced was all newer in the last few years to begin with like the controller it was a 500 amp before. Stock was gone years ago.
