Not every no-start is a bad battery. Our mobile diagnostic service uses professional digital testers to check your battery, alternator, starter and wiring so you replace only what actually needs replacing. It's the fastest way to stop guessing and stop buying parts you don't need.
Complete Electrical System Testing
We measure your battery's state of health, cold cranking amps and internal resistance; test alternator output under load and at idle; measure voltage drop on positive and ground cables; check starter current draw; and look for diode ripple that indicates a failing alternator.
When batteries keep dying overnight, we perform a parasitic draw test to find the circuit that's draining your battery while the vehicle is off — a common issue with aftermarket stereos, dash cams, trailer wiring and failing modules.
Printed Results You Can Trust
You'll receive clear test results explaining what's healthy and what isn't. If you choose to have a repair shop do other work, you'll have documented proof of what's wrong.
