Radiator (Cooling) Fan Relay

Some relays have battery voltage connected to terminal No. 30. Other haves battery voltage supplied to terminals No. 87 or No. 87A. See Figure . In de-energized position, relay should have continuity between terminals No. 87A and No. 30. Resistance value between terminals No. 85 and No. 86 should be 70-80 ohms for resistor type relays, or 81-91 ohms for diode type relays.
