Complete Auto Electrical Services for Richmond & Sugar Land Drivers
Garage Guys Automotive provides a full range of electrical diagnostics and repairs designed to restore reliable performance and safety to your vehicle.
New Battery Testing & Installation
A weak or failing battery is one of the most common causes of electrical problems. Before recommending a new battery, we perform a comprehensive evaluation to confirm whether the battery itself is the issue.
Our battery services include:
- Battery load testing
- CCA (cold cranking amps) measurement
- Visual inspection for leaks or corrosion
- Cleaning and protecting battery terminals
- High-quality battery replacement
- Charging system testing after installation
Your new battery should provide strong starts and stable electrical output—our installation ensures exactly that.
Alternator Repair & Charging System Diagnostics
Your alternator keeps the battery charged while supplying power to your vehicle’s electrical systems. When it fails, your car may lose power, lights may dim, and your engine may stall unexpectedly.
We provide complete alternator repair, including:
- Output and voltage regulation testing
- Alternator bearing and internal component inspection
- Belt and pulley inspection
- Alternator replacement when necessary
- Full charging system evaluation
Signs of alternator trouble include:
- Battery warning light on the dashboard
- Flickering headlights
- Electrical accessories shutting off
- Burning smell or whining noise under the hood
Proper alternator service prevents roadside breakdowns and protects your battery from premature failure.
Starter Repair & Starting System Service
If your engine doesn’t crank or you hear only clicking when trying to start your car, the starter may be failing. Accurate diagnosis is crucial, as similar symptoms can stem from battery or wiring issues.
Our starter repair services include:
- Starter motor testing
- Solenoid evaluation
- Relay and ignition switch testing
- Starter replacement
- Wiring and ground inspection
We identify and repair the true cause of starting issues, ensuring reliable engine cranking every time.

Faulty wiring can create unpredictable electrical issues that affect multiple systems at once. Our technicians are skilled at identifying and repairing even the most complicated wiring problems.
We repair:

- Poor grounding connections
- Melted insulation
- Loose connectors
- Faulty fuses and relays
Proper wiring repair improves reliability and prevents recurring issues.
Sensor & Control Module Diagnostics
Modern vehicles use dozens of sensors and electronic modules to maintain performance, safety, and drivability. When they malfunction, your vehicle may run poorly or display warning messages.
We diagnose and repair:
- Engine sensors (MAF, MAP, oxygen, crankshaft, camshaft)
- Transmission control modules
- ABS modules and wheel sensors
- Airbag and restraint system electronics
- Body control modules
- EVAP sensors
We use factory-capable equipment to read live data and pinpoint faults accurately.
