Testers, testing systems and methods of testing electrical components

A testing system, comprising:

• a plurality of adapters, each adapter comprising an adapter-component connector at one end of a cable and an adapter-tester connector at another end of the cable, wherein respective adapter-component connectors are for physically and electrically connecting to different electrical components;
• a tester for testing one of the electrical components, the tester comprising a tester connector for physically and electrically connecting to any one of the adapter-tester component connectors;
• a database of a plurality of testing specifications for a plurality of electrical components, wherein the database stores, for each testing specification, identification data that includes a resistance that defines an associated electrical component;
• an output device;
• at least one processor in operable communication with the database and the output device, wherein the at least one processor is configured to execute program instructions, wherein the program instructions are configured to cause the at least one processor to:
• identify a resistance of one of the electrical components connected to the tester connector using one of the plurality of adapters and provide corresponding identification data;
• retrieve a testing specification associated with the electrical component from the database using the identification data;
• command a test of the one of the electrical components according to the testing specification;
• and
• output an indication of a result of the test through the output device.

A method of testing an electrical component of a vehicle, the electrical component comprising a harness or a sensor, the method comprising:

• providing a plurality of adapters, each adapter comprising an adapter-component connector at one end of a cable and an adapter-tester connector at another end of the cable, wherein respective adapter-component connectors are for physically and electrically connecting to different electrical components of the vehicle;
• providing a tester for testing one of the electrical components, the tester comprising a tester connector for physically and electrically connecting to any one of the adapter-tester component connectors;
• providing a database of a plurality of testing specifications for a plurality of electrical components, wherein the database stores, for each testing specification, identification data that includes a resistance that defines an associated electrical component;
• providing an output device;
• identifying, via at least one processor, a resistance of one of the electrical components connected to the tester connector using one of the plurality of adapters and providing corresponding identification data;
• retrieving, via the at least one processor, a testing specification associated with the electrical component from the database using the identification data;
• commanding, via the at least one processor, a test of the one of the electrical components according to the testing specification;
• and
• outputting an indication of a result of the test through the output device.
