I followed the operational check as described at:
http://pages.prodigy.net/jforgione/MB_AAC.html
and the operational check shows normal. The step 8 shows reading from 8 - 60 volts to the motor according to the settings on the speed.
Trying to follow the procedures to read out the error codes, I can't get them to come up. It always displays the Operational check readings again.
