CONNECTOR CONTINUITY AND VOLTAGE TEST Required Special Tools: MB991219: Test Harness Set MD998459: Test Harness Follow the steps below to avoid causing poor connector contact and/or reduced waterproof performance of connectors when checking continuity and/or voltage at connectors of waterproof connectors.

Never backprobing a waterproof connector. Backprobing a connector may cause the terminals to corrode, deteriorating circuit performance. 1.If the circuit is to be checked in the closed state of use a special tool like MD998459.

Forcing the probe into the terminal may open the terminal, causing intermittent or poor contact and creating an open circuit. 2.If the connector is disconnected for checking and the facing part is the female pin side, use an appropriate male terminal for checking the contact pressure of connector pins (like MB991219). Do not simultaneously contact more than one terminal with the probe. Contacting two or more terminals at the same time may damage a circuit, possibly to the point of starting an electrical fire. 3.If the facing part is the male pin side, either carefully touch the probe to the pin so it does not accidently contact other pins, or use an appropriate female terminal.
