A check engine light, a derate or a truck that will not crank can all come down to a sensor, a connector or a wire. Finding that on site saves a tow and a guess.
What it covers
Computer diagnostics
We connect to the truck, read active and stored fault codes and trace them to the cause.
No start and no crank
Batteries, starters, cables and grounds tested and repaired.
Charging systems
Alternators and charging problems that drain batteries on the road.
Wiring and connectors
Shorts, chafed harnesses and corroded connectors found and fixed.
Lighting
Tractor and trailer lighting problems that put you at risk at the scale.
Reefer unit electrical
Electrical work on reefer units. No refrigeration work.
How it works
Call and describe it
Warning lights, codes on the dash or what the truck did right before it quit.
We plug in on site
Our mechanic connects diagnostic tools at the unit.
Trace the cause
We test circuits and parts to confirm the fault, not just read a code.
Repair and clear
We fix the problem, clear the codes and confirm the truck runs right.
Why drivers and fleets call us
Guessing at electrical problems gets expensive. A code tells you where to look, not always what failed. Testing on site means you pay for the part that actually broke.
For fleets, diagnostics fit right into a scheduled PM. Reading codes during routine service catches sensor and wiring problems before they turn into a derate on the interstate.
How pricing works
Diagnostic and electrical pricing depends on how long it takes to trace the fault, the parts needed, travel to the unit and the time of the call.
We share what we find before we make repairs. Repeat customers and fleet accounts get special rates.
Weather and road notes
Heat and humidity around Nashville are hard on batteries and wiring, and summer storms bring water into connectors.
Cold Iowa mornings expose weak batteries and bad grounds, and road salt along I-80 and I-380 corrodes connectors every winter.
Common questions
Can you read codes on the roadside?
Yes. We bring diagnostic tools to the truck and read codes on site.
My truck is in derate. Can you help?
Yes. Call and tell us what is showing on the dash. Many derate causes can be found and fixed on site.
Do you fix trailer wiring too?
Yes. We repair trailer lights, plugs and wiring as well.
Do you help with no starts?
Yes. We test batteries, starters, cables and grounds, and we do jump starts.
