Electrical faults

WrenchLane has launched a significant update integrating OEM data from Infopro Digital Automotive. Here is the quick breakdown: New Service Workflow: You can now plan and execute vehicle services according to OEM specs, featuring step-by-step guides for oil capacity, tightening torques, and required parts. Expanded Technical Data: The platform now includes technical drawings, repair manuals, and wiring diagrams. Pricing Update: These OEM features are free for all users until May 20th. After that, they will require a paid subscription (though diagnostics remain free). Coming Soon: Future updates will add specific workflows with OEM images and component placement data.

Most mechanics know the feeling. A car comes in with a check engine light. You pull the codes. Three fault codes stare back at you. Which one matters? Where do you start?

Electrical faults are among the hardest problems a workshop faces. A single symptom can point to dozens of possible causes, and chasing the wrong lead costs time and frustration. Most mechanics rely on experience, intuition, and trial-and-error—methods that work until they don't.
