ELECTRICAL
DELAY MODULE
Purpose
When operating the unit on rough terrain and the
operator comes off the seat, the seat delay module will
temporarily delay the engine shutting down, preventing
erratic engine operation.
The seat delay module is located under the control panel
on the LH fuel tank. (Fig. 358).

The seat delay module circuit board is made up of
several 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. 359).
