Starters & Alternators

Hearing a clicking sound when you turn the key? It might be the starter. If your lights are dimming or the battery drains while driving, it’s likely the alternator. We accurately test the entire charging system to pinpoint the exact component that needs replacing.

Electrical, A/C & Hybrid Diagnostics FAQ's

Does the battery replacement cost include disposal of the old one?

Environmental fees and safe disposal are standard parts of the quote. MGI Auto handles the recycling of the old lead-acid battery in accordance with hazardous waste regulations, ensuring the garage stays clean and the environment remains protected.

Testing is the only way to be sure. A comprehensive AVR (Audio Visual Rider) test is performed on the charging system. This isolates whether the battery is dead, or if the alternator simply isn’t recharging it, preventing unnecessary replacement of working parts.

Leaks are the primary reason for A/C failure. Simply adding refrigerant is a temporary fix. The service includes adding UV dye to the system, allowing technicians to visually spot and repair the escape point before refilling it with expensive Freon.
Safety is paramount with high-voltage systems. Specific training and insulated tools are required to service Hybrid and EV components. MGI Auto maintains the necessary certification to safely diagnose and repair these modern systems without voiding manufacturer warranties.

Duration depends on the engine layout. While a battery swap takes minutes, accessing a buried starter or alternator typically requires 2 to 4 hours. Same-day service is prioritized for these repairs to ensure the vehicle isn’t off the road overnight.

Why Choose MGI Auto?

Electrical ghosts can be frustrating and expensive if misdiagnosed. Instead of guessing and immediately swapping out costly components like alternators or batteries, MGI Auto relies on data. Using dealer-level schematics and advanced testing equipment, technicians trace the issue to the exact source, whether it’s a simple loose ground wire or a complex module failur, ensuring parts are only replaced when absolutely necessary.
