here is some clue to check about A axis brarke
in the software from 97 and up there is a parameter for set it
you can check the amplifier if you make M60 the light if it is AMC
turn from green to be light green
you can check the connection on the amplifier
if no' 6 have 2 wires and no' 9 conected with 2 wires one is bridge to no' 7
then you got a disable for the amplifier
there is no limit switch for that |
