Circuit Opening Relay
- With relay connected, ensure specified voltage is present at relay terminals. See CIRCUIT OPENING RELAY CIRCUIT VOLTAGE table. For location of circuit opening relays, see CIRCUIT OPENING RELAY LOCATION table.
- If voltages are okay, remove relay from vehicle. Check relay operation using a 12-volt battery source and perform resistance tests. See Fig 1 .
