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 fi lm
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. 664).

the module (Fig. 666). Connect the negative lead to
the battery negative terminal.
