Delay Module

Purpose

When operating the unit on rough terrain and the oper-
ator comes off the seat, the seat delay module will
temporarily delay the engine shutting down, preventing
erratic engine operation.

Location

The seat delay module is located under the seat as-
sembly behind the storage pocket (Fig. 527).

How It Works
The seat delay module circuit board is made up of sev-
eral different electrical components, such as a transient
voltage suppressor, capacitor, transistors, carbon film
resistors, diodes and a relay. These all work together
to supply seat switch temporary voltage to the circuit to
keep the engine running in case of short term voltage
interruption (Fig. 528).
