In reference to my earlier post, I wish to add the following.
I have disconnected the ‘motors’ from the sub-assembly and tried the gearing
on both halfs of the vehicle. The gearing for the wheels and the ‘dump’ function
seem to work correctly. With the violet wire holder at 12:00 wheels turn, 9:00
wheels turn, 3:00 wheels turn and at 6:00 the ‘dump’ function gearing works.
I have also tried to operate the “drive” motors not connected to anything (removed
from all “drive” axles), nothing. Could the ‘drive’ motors be defective?
