DCX400 correctly installed via LED display but motor doesn't respond

JohnnieB, I have the exact same set up as you - motor, solenoid, and batteries.

Except I have crown batteries running 48v and had the XCT500 until today because I was disappointed with the top speed compared to my DCX400.

So, I re-installed my DCX400, LED blinks 4 times and I have a solid green light.

However, the cart does not move. Any thoughts on this sir?

Thank you!
