[1] – Remove relay from load center.
[2] – Use ohmmeter to check continuity between relay terminals 87A and 30 (D and C).
[3] – Check for no continuity between terminals 30 and 87 (C and E).
[4] – Measure resistance between 85 and 86 (A and B).
[5] – Connect a jumper wire from battery positive (+) post to relay terminal 85 (A). Connect a jumper wire from relay terminal 86 (B) to ground (โ). Continuity should now exist between terminals 30 and 87 (C and E); no continuity between 30 and 87A (C and D).
Results:
If continuity is not correct, replace relay.
If resistance is approximately 680 ohms the relay coil is open, replace relay.
If resistance between terminals 85 and 86 (A and B) does not meet specification,
replace relay.
