5. Using a multimeter (ohms setting), measure coil re-
sistance between terminals 85 and 86 (Fig. 27). Resist-
ance should be between 70 and 90 ohms.
86 87A 87
6. Connect multimeter (ohms setting) leads to relay ter-
minals 30 and 87 (Fig. 27). 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.
85 30
7. Disconnect voltage from terminal 85 and multimeter
lead from terminal 87.

8. Connect multimeter (ohms setting) leads to relay ter-
minals 30 and 87A. Apply +12 VDC to terminal 85. The
relay should make and break continuity between termi-
nals 30 and 87A as +12 VDC is applied and removed
from terminal 85.
9. Disconnect voltage and multimeter leads from the
relay terminals.
10.Replace relay if testing determines that relay is faulty.
11. After testing is complete, secure relay to machine
