How It Works

When the seat is vacated, the switch is open and there
should be NO continuity between the two terminals.
When the seat is occupied, the swtich closes and there
should be continuity between the two terminals (Fig.
662).

Testing

1. Disconnect the switch from the wiring harness.
2. Using a VOM or test light, check fi rst to ensure there
is no continuity between either terminal, plunger out.
3. With the plunger pushed in, there should be contin-
uity between the terminals.

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. 663).
