I don't recall that, and I don't understand what "wiring it separately" 
would mean.  In the wiring diagram I got from Alltrax, the PTO wiring *is* 
completely separate from that for the controller.  

Did you have the controller connected to the tractor while you were 
charging 
it?  The manual says - in italics - that it shouldn't be, because the 
charger output can exceed the voltage ratings of the controller's 
components. This is the reason for the charge/run switch shown on the 
installation diagram.   If the controller was connected during charging, 
that would explain the overvoltage error code.  It certainly could have 
damaged the unit so that it would show symptoms of failure when powered up 
again.

If the controller wasn't connected during charging, a wiring error is 
certainly possible.  Another cause might be a wire that's pinched or has 
damaged insulation.  Did you strip out the old wiring and rewire the 
tractor?  The first sentence in the Alltrax manual is "Remove all relays, 
contactors, control boards, ribbon resistors and associated wiring from 
the 
Electric Tractor."  When I fitted the controller to my E-15, I took that 
to 
mean that I should remove the old control wiring.  I retained only the 
wiring to the brake switch and seat switch.
