How It Works

The switch is basically an on/off switch spring loaded to
return to off position. When turned to the ON position
with the PTO engaged, it activates circuits in the
KeyChoice™ Reverse Operating System reverse
module and allows the operator to mow in reverse
(Figure 244).

Testing

1. Disconnect the switch from the circuit.
2. With a mulitmeter, check the continuity across the
MVC-866F
two terminals. There should be NO continuity.
3. Turn the key to the "ON" position and hold, since
the switch is spring loaded. There should be
continuity across the two terminals.
