FAQs
How long does the test take on-site?
Most visits take 30–60 minutes depending on access and results.
Will this tell me definitively if it’s the battery, alternator, or starter?
Yes—the combined load, ripple, draw, and voltage-drop tests isolate the failing component; you’ll get written findings.
If I approve the repair, do you credit the test fee?
No. Diagnosis/testing is always billed separately and not applied toward repairs. Caleb's Car Care policy.
Do you test hybrids and start/stop systems?
We test the 12V system (including AGM/EFB batteries) and advise on repairs; we don’t service high-voltage packs.
How does the Ready-Set-Go™ Method apply here?
We keep the process step-by-step: confirm symptoms, run targeted tests, explain results, and give you options—fast and clear.

Our Diagnostic Philosophy
Our job is to find the failing link in your charging or starting system quickly and accurately. Using the Ready-Set-Go™ Method, we confirm your symptoms, run systematic tests, and document the results in writing. You’ll know if the fault is the battery, alternator, starter, or wiring—without guesswork.

Tools and Methods We Use
We use professional analyzers and proven test techniques to deliver accurate results:
Professional battery analyzer with state-of-health and CCA testing
Digital multimeter for voltage checks
Clamp ammeter for starter current-draw testing
Voltage-drop testing across main cables and grounds
OBD-II scan tool for charging/starting fault codes
Each test provides hard data that points directly to the failing component. Combined, these methods rule out guesswork and give you a clear repair path.
Why You Shouldn’t Wait
Charging and starting problems don’t heal themselves. A weak alternator can leave you stranded after dark. A bad starter can fail completely without warning. Ignoring the signs risks breakdowns, towing costs, and damage to sensitive electronics. A one-hour test today can prevent an expensive emergency tomorrow.
