Electrical Systems Diagnostics & Repair
Battery, alternator, wiring, and power distribution service for modern heavy-duty trucks.
Schedule an Electrical CheckWhen Electrical Service Matters
Your electrical system powers everything from engine control modules and lighting to ABS, sensors, climate control, and telematics. Failures can result in downtime, safety hazards, and diagnostic complexity.
Intervals & Triggers
- Full electrical inspection every 100,000-150,000 km, or annually
- At each PM visit, inspect battery health, grounds, harness integrity
- Inspect early if flickering lights, erratic cluster behavior, or starting issues
Indicators It’s Time for a Diagnostic Check
- Dim or flickering lights
- Difficulty starting or weak cranking
- Warning lights (battery, ABS, check-engine)
- Intermittent or phantom electrical faults
Common Issues We See
- Weak or failing batteries (age or sulfation)
- Alternator or voltage regulator failures
- Corroded or loose battery/ground connections
- Damaged or chafed wiring harnesses
- Blown fuses or failed relays
- Faulty power distribution modules (PDMs)
- Sensor or module malfunction from poor grounding
Winter Watch — Manitoba Conditions
- Battery capacity loss in cold (reduced CCA)
- Moisture freezing inside connectors or harnesses
- Corrosion acceleration from road salt or spray
- Voltage drops causing weak starts
- Insulation stiffening leading to intermittent faults
Preventive Tips
- Use batteries rated for high CCA
- Clean and seal terminals, inspect grounds
- Secure wiring and avoid contact with heat sources
- Apply dielectric grease on moisture-exposed connectors
- Verify charging voltage (13.5-14.7 V under load)
