RELAY - STARTER MOTOR 

DESCRIPTION 

STARTER RELAY 

The starter relay is an electromechanical device that switches battery current to the pull-in coil of the starter 
solenoid when ignition switch is turned to Start position. The starter relay is located in the Power Distribution 
Center (PDC) in the engine compartment. See PDC cover for relay identification and location. 

The starter relay is an International Standards Organization (ISO) relay. Relays conforming to ISO 
specifications have common physical dimensions, current capacities, terminal patterns, and terminal functions. 

The starter relay cannot be repaired or adjusted and, if faulty or damaged, it must be replaced. 

OPERATION 

STARTER RELAY 

The ISO relay consists of an electromagnetic coil, a resistor or diode, and three (two fixed and one movable) 
electrical contacts. The movable (common feed) relay contact is held against one of the fixed contacts (normally 
closed) by spring pressure. When electromagnetic coil is energized, it draws the movable contact away from 
normally closed fixed contact, and holds it against the other (normally open) fixed contact. 

When electromagnetic coil is de-energized, spring pressure returns movable contact to normally closed position. 
The resistor or diode is connected in parallel with electromagnetic coil within relay, and helps to dissipate 
voltage spikes produced when coil is de-energized.
