I'm coming at this from the controller instead of the vehicle.
(this was a fairly common controller in the material handling community at one time.)
Your model number 633T45312
633=Millipack
T=High power controller
4=48volt
5= 500-599 amp range
3= SEM regen (series electric motor with regenerative braking )
12=Vendor code ( Which is actually for "Club Car")
Uh , I dont see a "12 Flashes" code for that controller, it is vendor specific
( Its whatever the vendor wants it to be, but most likely its "Brush wear monitor" )
If I read your post right , you have two controllers and two motors.
Im assuming you have the DA8-4013 motors?
One of the issues with this motor is that if they sit a long time the brushes will jam in the holders and just barely hover over the commutator causing them to arc and "Burn Up" ( cook one of the brushes ) which is what I think happend to your motors.
What I suspect happened is
1. Bushes are jammed , one motor cooked a brush, melting the brush wear indicator inside the brush ( causing the code )
2. The other motor was stalling out because of the jammed brushes when you tried to drive on one motor, and it cooked a brush.
I'd try putting the repaired motors back in and see if it drives.
