I also have an Ultimaker Original. I also got the error 'Extruder switched off. MAXTEMP triggered'. At first thought i thought the motor of the extruder was broken, but after switching the cables with the X-Motor, i found out this motor worked. After switching the cables again, i still got the error.
This is a common problem - especially with older Ultimaker Originals (as the wiring works for a year or more and eventually breaks).
It's usually at the head of the printer at the connector. Did your wiring go through the black F shaped wire strain relief?
Quick fix is to just use the alternate wiring.
If instead you want to debug the problem, try turning it on and checking that the nozzle temp is 20C. Then push the test head to the 4 corners. Often this is enough to trigger MAXTEMP. If this isn't enough start poking the wires at the top of the print head - it's usually the connector on the tiny circuit board.
Alternatively the wire may have fallen off underneath the printer. The basic problem is the wiring from the tiny circuit board on top of the head to the circuit board underneath the printer.

UM Original or UM2? Please also update your location (say what country you are in) and your description (say what printers you have) in your profile settings.
This is an easy problem to fix but depends on the printer.
