HEAVY-DUTY ELECTRICAL & ELECTRONICS REPAIR
Power, Starting & Controls
TRACE THE PROBLEM THROUGH THE SYSTEM
ELECTRICAL AND ELECTRONICS DIAGNOSTICS FOR COMMERCIAL TRUCKS AND BUSES
Modern heavy-duty vehicles depend on electrical and electronic systems for starting, charging, engine management and the operation of numerous vehicle components.
A weak connection, damaged wire, failing sensor or charging-system problem can create intermittent symptoms that are difficult to identify without proper testing.
Bo’s Garage provides electrical and electronics diagnostics and repair for Class 6, 7 and 8 trucks, semis and select charter or tour buses.
STARTING & CHARGING
Battery, starter and alternator concerns evaluated
WIRING & CONNECTIONS
Circuits checked for damage, corrosion and poor connections
ELECTRONIC DIAGNOSTICS
Fault information reviewed to help locate system problems
Why Electrical Diagnosis Matters
ONE FAULT CAN CREATE SYMPTOMS ACROSS MULTIPLE SYSTEMS
TEST THE CIRCUIT BEFORE REPLACING THE COMPONENT
Electrical problems can be caused by low voltage, poor grounds, damaged wiring, corroded connections, blown fuses, failing relays or another component within the circuit.
A warning light or fault code may identify the affected system without confirming which component caused the failure.
Systematic testing helps narrow down the source and determine whether the concern is electrical, electronic or connected to another vehicle system.
ELECTRICAL WARNING SIGNS
Our Process
FROM INTERMITTENT SYMPTOM TO IDENTIFIED FAULT
SYSTEMATIC TESTING OF POWER, GROUND, CIRCUITS AND RELATED COMPONENTS
REVIEW THE SYMPTOMS
We discuss what stops working, when the problem occurs and whether it is constant or intermittent.
INSPECT POWER & CONNECTIONS
The battery, cables, grounds, fuses and visible wiring are checked as applicable.
TEST & DIAGNOSE
Related circuits, charging components, sensors or electronic information are evaluated to locate the likely fault.
REPAIR & VERIFY
Approved repairs are completed, followed by appropriate electrical and operational checks.
Heavy-Duty Electrical Systems
FROM STARTING POWER TO THE CONTROLS THAT MANAGE THE ENGINE
SERVICE BASED ON VEHICLE CONFIGURATION, SYMPTOMS AND TEST RESULTS
Depending on the findings, service may involve batteries, alternators, starters, cables, grounds, switches, relays, wiring, sensors, actuators or related electrical components.
Electrical configurations vary by vehicle and engine. Call with the year, make and model, engine manufacturer, warning lights and symptoms so we can confirm service availability.
