Expert Battery Services for Richmond & Sugar Land Drivers

A weak or failing battery is one of the most common causes of electrical problems. We evaluate your battery thoroughly before recommending replacement.

New Battery Testing & Installation

Before installing a new battery, we test your existing one to confirm whether it’s truly the source of the issue. Installing a battery without testing the alternator or wiring can lead to the same problem reappearing.

Our battery services include:

• Load testing

• Cold cranking amp (CCA) testing

• Visual inspection for corrosion or swelling

• Cleaning and protecting battery terminals

• Professional battery installation

• Charging system testing after installation

We install long-lasting, high-quality batteries designed for Texas heat and daily driving demands.

Alternator Repair & Charging System Diagnostics

Your alternator charges your battery and powers your electrical systems while the engine runs. When it fails, your vehicle may stall or lose power unexpectedly.

Professional Alternator Repair & Replacement

Our alternator repair services include:

• Alternator output testing

• Belt and pulley inspection

• Voltage regulation testing

• Alternator bearing evaluation

• Complete alternator replacement when necessary

If your alternator fails, warning signs typically include:

• Battery light on the dashboard

• Dimming lights

• Weak electrical performance

• Dead battery even after replacement

We diagnose the issue accurately and repair or replace the alternator using high-quality parts.

Starter Repair & Starting System Service

The starter is responsible for turning over the engine. If it fails, your vehicle may not start at all—even with a fully charged battery.

Complete Starter Repair Solutions

Our starter repair services include:

• Starter motor testing

• Solenoid evaluation

• Ignition switch testing

• Relay and fuse inspection

• Starter replacement

• Ground and wiring inspection

Signs of starter failure include:

• Clicking sound when turning the key

• Grinding noise during startup

• Engine doesn’t crank at all

• Starter remains engaged after engine starts

We identify the root cause and fix it fast.

Electrical Wiring & Connection Repair

Sometimes the issue isn’t the battery, starter, or alternator—it’s the wiring or electrical connections linking them together.

We repair:

• Corroded wires

• Damaged connectors

• Poor ground connections

• Melted insulation

• Rodent-chewed wiring

• Faulty fuses and relays

We ensure every electrical pathway is safe and functioning as intended.

Full Charging & Starting System Inspection

Electrical problems are often misdiagnosed without proper testing. At Garage Guys Automotive, we check the entire system to identify the exact source of the problem.

Our comprehensive diagnostic includes:

• Battery health testing

• Alternator output and voltage checks

• Starter draw analysis

• Ground and terminal inspection

• Wiring continuity tests

• Fuse and relay evaluation

This ensures we recommend the correct repair the first time.

Preventative Electrical Maintenance

Preventing electrical failures is easier—and less expensive—than repairing them after they occur. We recommend:

• Testing your battery twice a year

• Replacing old or cracked belts

• Checking alternator output during oil changes

• Cleaning and tightening battery terminals

• Inspecting wiring regularly

• Addressing warning lights immediately

Good maintenance extends the life of your electrical components and keeps your vehicle dependable.
