Intermittent electrical issues in vehicles are difficult to diagnose because they don't always present when testing, requiring extensive manual checks.

Existing diagnostic tools test components statically but don't simulate intermittent failures under load or temperature variation.

Workarounds Described

manually checks connections and grounds
manually load tests alternator under different RPMs and loads

Implied Software Gaps

Automated intermittent fault simulation and logging tool that replicates driving stresses
Performance dashboard that continuously monitors electrical system during test drives

App Concept

FaultFinder Pro

A diagnostic tool that simulates driving conditions (varying RPM, electrical load, temperature) to catch intermittent electrical faults. It performs automated parasitic draw tests, ground resistance checks, and continuous logging, eliminating the need for manual guesswork.

Key Features

Automated intermittent fault simulation under load and temperature
Continuous voltage logging with anomaly detection
Guided parasitic draw test with isolation suggestions
Ground and connection resistance sweep verification

Target Users: Professional mechanics at independent shops or dealerships diagnosing intermittent vehicle electrical issues

Revenue Model: $299 one-time hardware unit plus $29/mo software subscription for cloud logging and updates
