Our Electrical Diagnostic Process
We begin with a digital diagnostic assessment that connects to the vehicle’s onboard computer and retrieves stored error codes. Our technicians also visually inspect relevant components for visible concerns. A code shows where the computer detected a problem, but it doesn’t necessarily identify the failed part, so both steps matter.
After the assessment, a service advisor explains the findings and recommendations in clear terms. You’ll receive a Digital Vehicle Inspection, or DVI, an electronic report that lets you review and approve recommended work directly.
Once you approve the work, we can complete it immediately or schedule it based on parts and customer availability. No repair moves forward until you’ve reviewed the recommendation.
1. Schedule Your Appointment
Whether scheduling online or over the phone be sure and let us know what you're experiencing so we can provide fast and accurate service advice.
2. Diagnostics and Inspections
Drop off your vehicle and the shop will get to work with inspections and diagnostics using the same equipment as the manufacturers to determine issues and next steps.
3. Digital Vehicle Inspection Report and Estimate
Following the diagnosis we will text you a digital vehicle inspection report, containing pictures and videos of our findings and recommendations.
4. Review and Approval
A service advisor will reach out to walk you through the findings and recommendations to determine how you would like to proceed, or you can approve work directly in your DVI.
5. Work Performed or Scheduled
Most work can be completed immediately, or scheduled based on parts and customer availability.
Battery Checks for Lockport Winters
Harsh winters in Lockport can affect vehicle batteries, tires, and fluids. We recommend a basic battery and fluid check every six months so drivers can monitor these systems before severe weather places additional demands on the vehicle.
Our battery service includes testing voltage and cleaning the terminals to help prevent no-start situations. We also perform a battery load test to measure how the battery responds while supplying power under demand. Together, these checks provide a clearer picture of battery health than appearance alone.
Warranty Coverage & Convenient Service Options
Electrical System work we perform is covered by the 3-year/36,000-mile Nice Difference® warranty. Coverage applies to all work performed and is honored at every Christian Brothers Automotive Lockport nationwide, regardless of which branch completed the original service.
We offer free shuttle service to reduce disruption while your vehicle is being serviced. If you plan to wait, free Wi-Fi is available during your visit. Ask about either option when scheduling your appointment.
Warning Signs of a Vehicle Electrical Problem
Electrical symptoms can overlap, so a warning sign alone doesn’t confirm that the battery, alternator, starter, or another component has failed. A diagnostic assessment can narrow down the cause when you notice changes in starting, lighting, accessories, or dashboard operation.
Common reasons to arrange an electrical diagnostic appointment include:
- Dim or flickering interior or exterior lights
- A clicking sound or no-start condition when turning the key
- A radio, GPS, or other electronic accessory that stops working correctly
- A burning smell associated with electrical operation
- An illuminated check engine light or another warning light
A burning smell warrants prompt attention. When it’s safe, turn off the vehicle and contact us for guidance rather than continuing to operate equipment that may be involved.
How the Battery, Alternator & Starter Work
The battery supplies the power needed to start the vehicle and operate accessories when the engine isn’t running. A weak or discharged battery may therefore affect both starting and accessory operation.
While the engine runs, the alternator supplies electrical power and recharges the battery. The starter has a different job: it draws power from the battery to crank the engine. Because these components work together, similar starting symptoms can have different causes and should be tested before parts are replaced.

Our contact form makes it easy to request electrical diagnosis or repair. We’ll document our findings and explain the recommendations so you can decide whether to authorize the work.

Components Within a Vehicle Electrical System
A vehicle’s electrical network extends beyond its starting and charging components. Wiring distributes power and signals throughout the vehicle, while fuses protect circuits from excessive current. These circuits serve lights, power windows and locks, climate-control functions, vehicle accessories, and instrument systems.
We troubleshoot battery failures, alternator issues, and other electrical faults. As part of that work, we can connect diagnostic equipment to the onboard computer and retrieve diagnostic trouble codes, or DTCs. The computer generates these records when it detects operation outside the expected range.
Those codes provide direction, but they don’t replace inspection and testing. We consider stored information alongside the vehicle’s symptoms and the condition of relevant components before presenting our findings.
