5. Disconnect voltage and multimeter leads from relay

terminals (Fig. 383).

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.

3. Connect multimeter (ohms setting) leads to relay

terminals 30 and 87. Ground terminal 86 and apply

+12 VDC to 85. The relay should make and break

continuity between terminals 30 and 87 when 12

VDC is applied and removed from terminal 85.

4. Connect multimeter (ohms setting) leads to relay

terminals 30 and 87a. Apply +12VDC to terminal

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

terminal.

PTO Switch

Purpose

The PTO (Power Take Off) switch is typically used to

activate the Electric PTO Clutch and to function as part

of the safety interlock system.
