Causal Diagramming

Causal Diagramming We use wiring diagrams in a number of diagnostics, when we aren't careful, they can on occasion lead us to generate decisions which aren't accurate, be responsible for wasted diagnostic time, unnecessary parts costs with the replacing parts which are not defective, and even missing a simple repair.

Today, the wiring diagram necessary to support the repair procedure is included within it or a hyperlink is provided to the perfect SYSTEM WIRING DIAGRAM article. By way of example, the wiring diagram to get a Ford EEC-IV system may be incorporated into ENGINE PERFORMANCE and WIRING DIAGRAMS articles for Ford Motor Co. The wiring diagram for your cruise control system could be included in ACCESSORIES & EQUIPMENT section for the exact vehicle manufacturer, plus the wiring diagram a great anti-lock brake system could possibly be included in BRAKES and WIRING DIAGRAMS for the actual manufacturer.

Inside my recent multi-part series on automotive electrical systems (which included primers on how electricity works and how to utilize multimeter), I gave a short troubleshooting example in which We used a multimeter to verify that voltage was present. In case your device—say, an electric motor—isn't working, first see whether voltage is reaching it as soon as the switch that powers the system is turned on. If voltage is present at the device's positive terminal, test for continuity between wire to the device's negative terminal and ground (first the body of the vehicle, and therefore the negative battery terminal). If it passes those tests, conduct a voltage drop test to look for an increased resistance failure. If the voltage drop test shows no problem, the set up is toast, like this Causal Diagramming?
