F (25



C) resistance should be approximately 80,470 ohms. If

resistance deviates greatly, replace sensor.

         RELAYS

         4-Terminal Relay

         1) Either round or square relays may be used. Testing is same

for either relay. Remove relay from holder. Using an ohmmeter, ensure

continuity exists between terminals No. 2 and 4 and does not exist

between terminals No. 1 and 3. See Fig. 9.

         2) Connect battery voltage to terminal No. 2, and ground

terminalNo. 4. Ensure continuity exists between terminals No. 1 and 3.

If continuity is not as specified, replace relay.

         6-Terminal Relay

         Remove relay from holder. Using an ohmmeter, ensure

continuity exists between terminals No. 2 and 5 and terminals No. 1

and 3 and does not exist between terminals No. 3 and 6. Connect

battery voltage to terminal No. 2, and ground terminal No. 5. Ensure

continuity exists between terminals No. 3 and 6 and does not exist

between terminals No. 1 and 3. See Fig. 10. If continuity is not as

specified, replace relay.
