Don’t Ignore These Warning Signs
Electrical problems rarely fix themselves. Early detection and repair can prevent
costly breakdowns and dangerous situations.
Immediate Action Required
- Burning smell from electrical components
- Visible sparks or smoke
- Complete electrical failure
- Battery extremely hot to touch
Pull over safely and call immediately. Do not continue driving.
Schedule Service Soon
- Dimming or flickering lights
- Slow engine cranking
- Battery warning light on
- Multiple jump starts needed
These indicate developing problems. Schedule service to prevent failure.
Keep Watch
- Accessories working intermittently
- Slight delay when starting
- Dashboard lights dim when idling
- Battery more than 3 years old
Note any changes and mention during next service.
Complete Electrical System Expertise
Modern diesel trucks have complex electrical systems. We’re equipped to handle everything from basic repairs to advanced diagnostics.
Starting System
Your truck won’t start? We diagnose and repair starters, solenoids, ignition switches, and related wiring. We test cranking amps, voltage drop, and component integrity to ensure reliable starting every time.
Charging System
Keep your batteries charged and systems powered. We test alternator output, replace voltage regulators, check belt tension, and ensure your charging system maintains proper voltage under all conditions.
🔋
Battery Service
More than just replacement – we perform load testing, clean connections, check specific gravity, and ensure proper battery box ventilation. We stock heavy-duty batteries for immediate replacement.
💡
Lighting Systems
Stay legal and safe with properly functioning lights. We repair headlights, marker lights, turn signals, brake lights, and interior lighting. LED upgrades available for better visibility and longevity.
⚙️
ECM & Electronics
Computer problems require computer solutions. We perform ECM diagnostics, software updates, parameter programming, and module replacement for engine, transmission, and body controllers.
🔌
Wiring Repairs
From simple shorts to complex harness issues, we trace circuits, repair damaged wiring, and solve intermittent problems. We use professional tools to ensure lasting repairs that won’t fail.
Our Systematic Diagnostic Approach
Electrical problems require methodical troubleshooting. Here’s how we find and fix issues efficiently:
Listen & Learn
We start by listening to your description of the problem. When does it happen? What are the symptoms? Any recent work done? Your observations guide our diagnostic strategy.
Visual Inspection
Many electrical problems have visible clues. We check for corrosion, loose connections, damaged wiring, burnt components, and signs of previous repairs that might be causing issues.
Systematic Testing
Using professional multimeters, amp clamps, and circuit testers, we measure voltage, amperage, resistance, and continuity to pinpoint problems without guesswork.
Component Testing
We test individual components under load conditions. A battery might show 12.6 volts but fail under load. An alternator might charge at idle but not at highway speeds.
Clear Communication
We show you test results, explain what we found, and discuss repair options. You’ll understand the problem and the solution before we begin any work.
Our Promise to You
No Parts Changing Guesswork
We’ve seen too many trucks with new batteries, alternators, and starters that still won’t start. We diagnose first, identify the real problem, then fix it right. You won’t pay for parts you don’t need.
Safety First Approach
Electrical work can be dangerous. We follow proper procedures, use insulated tools, and ensure all repairs meet safety standards. Your safety and our technicians’ safety are never compromised.
Quality Parts & Warranty
We use OEM-quality parts that meet or exceed manufacturer specifications. All our electrical repairs come with warranty coverage. If a part fails, we’ll replace it at no charge.
Preventive Recommendations
Beyond fixing the immediate problem, we’ll inspect related components and advise you on preventing future failures. A little maintenance now prevents big problems later.
Service Coverage Area
We provide mobile engine diagnostics and repair throughout 401 an Hwy 1 (west coast):

Frequently Asked Questions
What are common signs of electrical problems?
Warning signs include dimming lights, difficulty starting, battery warning lights, electrical accessories not working, or burning smells. Also watch for clicking sounds when starting, lights that brighten when revving the engine, or multiple blown fuses.
Can you reprogram ECMs on-site?
Yes, we have the equipment and software to perform ECM diagnostics, programming, and parameter changes for most diesel engines right at your location. This includes Cummins, Detroit, CAT, and International systems.
Do you stock electrical parts?
We carry common electrical components including batteries, alternators, starters, fuses, relays, and wiring supplies. For specialized parts, we can source and install them quickly, often the same day.
