What it is

A van-based service that finds and repairs electrical problems in cars and light trucks: dead batteries, alternators, starters, faulty wiring, lights, fuses and warning-light issues.

Your first three steps

  1. Build or confirm your skills with ASE electrical certification or shop experience, and buy a quality multimeter and scan tool
  2. Fit out a van or truck with core tools, a battery tester and common parts, then price jobs against local shops
  3. Register your business, get insurance, and post on Google Business Profile and local community groups
Who pays

Car owners who can't or don't want to tow a vehicle to a shop, plus small businesses with work vans and local fleets.

How it makes money

A diagnostic or call-out fee plus labor and parts markup on each job, with a flat price for common jobs like battery or alternator replacement.
