NOTE: See page 23-86 for turn signal/hazard relay inputIESI.
Normally-opon type:
'1. Check for continuity between the terminats.. There should be continuity between the No. I 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.
