5. Using a multimeter, verify that coil resistance be-
tween terminals 86 and 85 is approximately 72 ohms.
6. Connect multimeter (ohms setting) leads to relay ter-
minals 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. Disconnect voltage and test leads from the relay ter-
minals.
8. Secure relay to mounting bracket and connect wire
harness connector to relay.
9. Secure all removed components to machine.
10.Connect positive (+) cable to battery and then con-
nect negative (--) cable to battery (see Battery Service
in the Service and Repairs section of this chapter).
