The rotating
speed control may have a hung up micro switch......
The printed
circuit card has a bad scr or diode.
Does 1A and 2A
pick up? You should hear them....if not, check coil
resistance.

engage in first, both forward and reverse. Tractor has been setting for
quite some time, could the speed control need cleaned? Still working on
the frozen brake shaft.
