The starting and charging system powers every electrical function in your vehicle. The starter motor draws current from the battery to turn the engine over, while the alternator recharges the battery and supplies voltage to all systems while the engine runs. When either component begins to fail, you’ll experience slow cranking, dim lighting, or even a dead battery after short drives.

Common warning signs include:

• Clicking or grinding noise when starting
• Dim headlights or electrical accessories
• Battery light or charging system warning on the dash
• Frequent jump-starts or dead batteries
• Burning smell or whining sound under the hood

Our technicians perform accurate voltage drop testing and current draw analysis to isolate faults in the starter, alternator, or wiring—eliminating guesswork.

At The Garage MKG, we don’t just replace parts—we test and confirm what’s actually failing. Using digital multimeters, load testers, and OEM scan tools, our ASE-certified technicians measure cranking amperage, alternator output, and ground integrity before recommending repairs.

Our process includes:

• Battery and cable inspection
• Starter amperage and voltage-drop testing
• Alternator load and output verification
• Belt and pulley inspection for mechanical drag
• Post-repair charging system validation

When replacement is required, we install high-quality OEM or equivalent components, ensuring long-term reliability and proper voltage regulation. Each repair is documented in your Complete Vehicle Health Report with photos, voltage readings, and technician notes.
