1. Most of the connections between harnesses are made with plastic plugs. If these connections are not tight, they can cause several different problems at one time (several different circuits go through one plug). They can also cause intermittent (come and go problems). Make sure the plugs are tight before other tests are done.2. The 5P7277 Voltage Tester can be used to check a circuit for voltage. The 8S4627 Circuit Tester can be used to test circuits without voltage for continuity. The light in the 8S4627 Circuit Tester is dim (not much light) with 10 ohms resistance in the circuit. It becomes brighter (more light) with less resistance.3. The 6V3030 Digital Multimeter can be used to measure circuit voltage or circuit resistance (continuity). The instructions that come with the multimeter tell how to use it.
5P7277 VOLTAGE TESTER4. Failure of an electrical component can cause or be caused by the failure of one or more other components. Always find the cause of failure of an electrical component before making a replacement.
