:
The engine does not shut down when shifting into
reverse when the reverse caution mode is not
activated.
OR
The engine does not shut down when the operator
leaves the seat with the PTO on.
Connect an ohmmeter between the magneto terminal
(yellow/black wire) at the module and ground. With the
key in the "ON" or "Reverse Caution" position, PTO
engaged, and the seat occupied the meter should
show continuity when the shift lever is placed in
reverse, or the operator gets out of the seat.
a) Continuity: the module is OK, check the
associated wiring.
b) No continuity: Remove the connector from
the module (Figure 8). Using a multimeter
check the electrical circuits for the conditions
listed in the table below.
If the circuit conditions are met, replace the module.
