Testing Relays with 5 Terminals (continued)
Note:
Prior to taking small resistance readings with a digital multimeter, short
the meter test leads together. The meter will display a small resistance value
(usually 0.5 ohms or less). This resistance is due to the internal resistance of
the meter and test leads. Subtract this value from the measured value for
the tested component.
5. Using a multimeter, verify that coil resistance between terminals 85 and 86 is
from 71 to 88 ohms.
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. 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.
8. Replace the relay if necessary.
9. If the relay tests correctly and a circuit problem still exists, check the wire
harnesses; refer to
Appendix A (page A–1)
.
10. Connect the wire harness, install any items removed to access the relay, and
connect the battery ground cable.
