Bad MCOR or something else?

Trying to get the cart up and running. 2006 Precedent

Replaced all the batteries with 6-8v system. New solenoid, new tow/run switch, dioide, pre charge resistor, new f&r switch, new battery cables, new fuse.

Completely removed the OBC and jumped it (to get it out of lockout mode)
Key switch also is working.

Reading 50v on the dash voltmeter (also new).

I do get a beep in reverse.

Jumped the motor with a 12v battery and the motor spins.

But car does not move. I do NOT hear the soleniod "click" at all when accelerator is pressed.

Bad MCOR or controller? MCOR is original. The Curtis 1510 controller is also original.
