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 our computer diagnostics and electrical 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.
How it works in Cedar Rapids, IA and Nashville, TN
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 call Wells Mobile
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.
Because we run 24/7 roadside service, we see electrical failures in every kind of weather and know where they tend to hide.
For fleets, diagnostics fit right into a scheduled PM. Reading codes during routine service catches sensor and wiring problems early, before they turn into a derate or a no start on the interstate.
What affects the price
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.
Weather and road notes
Cold Iowa mornings expose weak batteries and bad grounds. Road salt along I-80 and I-380 corrodes connectors and harnesses every winter.
Heat and humidity around Nashville are hard on batteries and wiring too, and summer storms bring water intrusion into connectors.
Diagnostics and Electrical 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.
