ELECTRICAL SYSTEM
*NOTE:
A KSI (key switch input) system problem is a speci
fi
c HPD (high pedal disable) type operational fault, caused by the operator activating
the Fwd/Rev drive pedal before turning on the main key switch or activating the throttle before sitting on the seat. This can be cleared by returning
the operator’s drive pedal to neutral and cycling the key switch OFF and ON.
