Check the resistance.

Using an ohmmeter, measure the resistance between the terminals.

Standard

RESISTANCE SPECIFICATION

Tester Connection	Specified Condition
3 - 5	10 kΩ or higher
3 - 5	Below 1 Ω (Apply battery voltage to terminals 1 and 2)

If the result is not as specified, replace the circuit opening relay.
