Power Relays
Relay Test
Turn Signal/Hazard Relay:
See page 23-172
Normally-open type:
1. Check for continuity between the terminals.. There should be continujty between the No. 1 andNo.3 terminals when power and ground are con-nected to the No. 2 and No. 4 terminals.. There should be no continuity between the No. 1and No. 3 terminals when power is disconnected.
