Testing - Toro 22317 Service Manual

Testing

1. Disconnect the relay from the harness.
2. Verify the coil resistance between terminals 85 and
86 with a multimeter (ohms setting). Resistance
should be from 70 to 90 ohms. There should be
continuity between terminals 87a and 30 (Fig. 2048).
3. Connect the 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
(Fig. 2048).
4. Connect the multimeter (ohms setting) leads to relay
terminals 30 and 87a. Apply +12VDC to terminals
85. With terminal 86 still grounded, the relay should
break and make continuity between terminals 30
and 87a as 12 VDC is applied and removed from the
terminal (Fig. 2048).
5. Disconnect voltage and multimeter leads from relay
terminals.
