code 11 should only happen when the handset is plugged in and in diagnostic mode, but it indicates:
Incorrect traction motor wiring,
or motor shorted to frame,
or controller shorted to B- (Check by disconnecting motor cables at controller and check resistance from controller motor terminals to B- It should be 1 megohm or more)

code 32 is:
Main tips are welded or the main contactor driver is shorted.

code 34 is what I posted above.

Seeing as you replaced the contactor, are you sure it was an exact replacement?
