Iso Relays - Dodge Charger Pursuit 2011 Upfitter Manual

ISO Relays

ISO relays conform to the specifications of the International Organization for Standardization for
common size and terminal pattern. ISO relays are used in many applications such as the starter,
horn, electric fan, air conditioning clutch, auto shut down, and fuel pump circuits.
Relay connection terminals are defined as follows:
• Terminal 30 is usually connected to battery voltage. This battery voltage source can be
switched on or off by the ignition switch, or un-switched, connected directly to the battery.
• Terminal 87A is connected to Terminal 30 in the de-energized position.
• Terminal 87 is connected to Terminal 30 in the energized position. When energized, the
relay supplies battery voltage to Terminal 87, or removes battery voltage from a device
connected to Terminal 87A .
• Terminal 86 is connected to the electromagnet and is usually connected to a switched
battery voltage source.
• Terminal 85 is connected to the electromagnet and is usually connected to a switched or
un-switched ground.
