go through all the fuses with voltmeter
disconnect the car battery all the time

Implied Software Gaps

A tool that automatically identifies which circuit is draining the battery without manual fuse-by-fuse testing
A notification system that alerts the owner when a parasitic drain is detected before the battery dies

App Concept

Parasitic Drain Finder

A smartphone-connected tool that clips onto the vehicle's fuse box and identifies which circuit is drawing current when the car is off. Instead of manually probing each fuse, the app shows a real-time graph of current draw and pinpoints the offending circuit in minutes.

Key Features

Plug-and-play fuse box adapter that monitors current on all circuits simultaneously
Mobile app with real-time current draw graph and alerts for abnormal drain
Automatic circuit labeling based on fuse map database (OEM-specific)
Step-by-step guided diagnostics to narrow down drain source

Target Users: DIY car owners and amateur mechanics with late-model vehicles experiencing unexplained battery drain

Revenue Model: $129 for the hardware adapter + $9.99/mo app subscription or $199 one-time purchase with lifetime app access
