Interrupt Relay: Inspection

Measure the interrupt relay resistance between terminals (indicated in the table below) when connecting terminal No. 4 to battery positive terminal and terminal No. 2 to battery ground terminal.

TERMINAL REFERENCE

Current	Terminal No.	Standard
Flow	1 - 3	More than 1 MΩ
Flow	1 - 5	Less than 1 Ω
No flow	1 - 3	Less than 1 Ω
No flow	1 - 5	More than 1 MΩ
