6. Connect multimeter (ohms setting) leads to relay terminals 30 and 87.
Ground terminal 86 and apply +12 VDC to terminal 85. The relay should
make and break continuity between terminals 30 and 87 as +12 VDC is
applied and removed from terminal 85.
7. Verify infinite resistance (no continuity) exists between terminals 30 and 87.
8. Connect multimeter (ohms setting) leads to relay terminals 30 and 87A. Apply
+12 VDC to terminal 85. The relay should make and break continuity between
terminals 30 and 87A as +12 VDC is applied and removed from terminal 85.
9. Replace the relay if necessary.
10. If the relay tests correctly and a circuit problem still exists, check the wire
harnesses; refer to
11. Connect the wire harness and connect the battery ground cable.
