Motor Relay
- Remove motor relay from HCU. Using an ohmmeter, measure resistance between motor relay terminals No. 85 and 86. See Fig 1
. Resistance should be 30-60 ohms. Check for continuity between terminals No. 30 and 87. Continuity should not exist.
- Connect positive lead of 12-volt power source to terminal No. 85, and negative lead to terminal No. 86. Check for continuity between terminals No. 30 and 87. Continuity should exist. If relay does not test as specified, replace relay.
