Backprobing Spring-Loaded Lock Connectors

When checking voltage or resistance on this type of connector the first time, it is necessary to remove the retainer to insert the tester probe from the wire side. It is not necessary to reinstall the removed retainer; the terminals will stay locked in the connector housing.




To remove the retainer, insert a flat-tip screwdriver between the connector body and the retainer, then carefully pry out the retainer. Take care not to break the connector.
