Harness Failures: What’s to Blame? | 2017 04 13 | Assembly ... As harnesses evolved in complexity, so did the need for testing. By the 1950s, harness manufacturers—particularly those serving the automotive industry—began using telephone stepper switches (relays) to test the continuity of each harness wire and verify its location in a connector. Typical Connector Failure Modes and Mechanisms The “Connector Basics” series from APEX Electrical Interconnection Consultants continues with an introductory look at typical connector failure modes and mechanisms. When we discuss connector failure, we need to refine the concept into two distinct components – failure modes and failure mechanisms. How do we define “failure”? Automotive Circuit Failures Classic Car Electrical ... If you imagine wires running together in old cloth wrapped harnesses, chafing against clips and each other, rubbing off their insulation until bare wire is touching bare wire, you can see how if, for example, you hit the brakes and the fan comes on, this kind of short to power is usually the root cause. Failure Mode #4: ponent Failure .mtain Failure Mode Effects and Criticality ... Failure Mode Effects and Criticality Analysis (FMECA) The Failure Modes and Effect Analysis, commonly referred to a FMEA, is one of the most utilized methods for conducting reliability analyses. The Failure Modes and Effects Criticality ... wiring harnesses, electronic sensor and firing mechanism. Failure Modes Wire ends yield failure clues | EDN A nick, scratch, or abrasion in the wire surface concentrates stress at this point and increases the susceptibility of the wire to tensile or bending stress. Intentionally nicking the wire surface with a sharp knife and then cyclically bending the wire until fatigue failure occurred produced the wire end shown in Figure 8. This wire end shows ... Minimum bend radius as applied to aircraft wire system ... Knowledge of minimum bend radius can reduce wire system degradation. These stresses can come from clamps that are too tight, over compressed harnesses protection sleeving, or poor routing. One method to reduce this potential mechanical strain in harness routing, is to ensure that all harnesses are maintaining a minimum bend radius.
