There are 2 relays:
1. Start Relay
2. Kill Relay
1. Start Relay: Functions as an electronic switch. Once
the safety connections are met, the relay will activate
completing the circuit to the starter solenoid.
2. Kill Relay: Functions like an electronic switch. If
all conditions for operation are not met, the relay
closes, grounding the engine ignition system.

The relays are located under the panel assembly (Fig.
380).
A relay is an electrically actuated switch.
1. Coil: Terminals 85 and 86 are connected to a coil.
Applying 12 volts to these terminals energizes the
coil turning it into an electromagnet.
2. Switch: Terminals 30, 87 and 87a are actually part of
a single pole, double throw (SPDT) switch. Terminal
30 is the common lead. The switch is spring loaded
so that 30 and 87a are connected when the coil is
not energized, the switch is “thrown” and 30 and 87
are connected (Fig. 381).
