Use of Circuit Testing Tools

You should only use a test lamp when a diagnostic procedure refers to it's use. You should know how to use fused jumper wires to test components and allow DMM readings without damaging terminals. You should know how to use Connector Test Adapter Kit, J 35616 and use it whenever diagnostic procedures call for front probing any connector.
