1970 Pontiac Lemans Wiring Diagram We use wiring diagrams in a number of diagnostics, but if we're not careful, they can on occasion lead us to make decisions that are not accurate, resulted in wasted diagnostic time, unnecessary parts costs for the replacing parts aren't defective, or even missing a fairly easy repair.

Today, the wiring diagram required to support confirmed repair procedure is roofed within that article or a web link is supplied to the proper SYSTEM WIRING DIAGRAM article. As an example, the wiring diagram for just a Ford EEC-IV system could be a part of ENGINE PERFORMANCE and WIRING DIAGRAMS articles for Ford Motor Co. The wiring diagram to get a cruise control system can be incorporated into ACCESSORIES & EQUIPMENT section for the unique vehicle manufacturer, and the wiring diagram a great anti-lock brake system may be a part of BRAKES and WIRING DIAGRAMS for the actual manufacturer.

In my recent multi-part series on automotive electrical systems (which included primers on how electricity works and how to use a multimeter), I gave this short troubleshooting example in which I often went a multimeter to substantiate that voltage was present. If your device—say, a power motor—isn't working, first decide if voltage is reaching it if the switch that powers the set up is turned on. If voltage is present at the device's positive terminal, test for continuity between wire to your device's negative terminal and ground (first our body of the vehicle, while the negative battery terminal). If it passes those tests, conduct a voltage drop test to look for a high resistance failure. Should the voltage drop test shows no worries, the set up is toast, such as 1970 Pontiac Lemans Wiring Diagram?
