[3] TESTING WITH A CIRCUIT TESTER

Testing Voltage and Continuity at a Connector
To prevent damage to the connector terminal contacts and/or
reducing the water-proofing of the connector when testing a
connector for voltage and/or continuity, follow the guidelines below.
1. General (not waterproof) connectors
• Insert the test lead from the harness side. Female terminals
are particularly prone to damage so always insert the test
leads from the harness side.
• ECU connector terminal pins are extremely small, so do not
try and force a test lead in; use the special tool.
2. Waterproof connectors
• If you try to test the circuit when it is in a closed state and
force the test leads in from the harness side, it will reduce
the effectiveness of its waterproofing, leading to corrosion,
so never do this.
• When testing a male pin, touch the test lead directly to the
pin. In this situation, be very careful not to short circuit
across connector terminals.
3. Special tools
• When the connector pin holes are smaller than the test
leads, use thin wires.
