Liquid-Cooled Engine Model: Three relays located on

the right rear radiator support arms, next to the ROPS

(Fig. 323).

1. Coil: Terminals 85 and 86 are connected to an

internal coil. Applying 12 volts to either terminal

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 terminals 30 and 87a are connected

when the relay is not energized. When the relay is

energized, the magnetic eld overcomes the spring

loaded switch and connects terminals 30 and 87

(Fig 325).

A relay is an electrically actuated switch (Fig. 324).
