Interactive symptom-based diagnostic flow
OBD-II and multimeter data logging
Known issue database for specific models
Guided voltage drop and ground testing
Report generation for mechanics

Target Users: DIY car owners and auto mechanics dealing with intermittent electrical issues on older vehicles

Revenue Model: $9.99 per diagnostic session or $19.99/mo subscription for unlimited access
