Alternator Test
Not sure if it’s your alternator?
Alternators can be deceiving. If your vehicle is experiencing flickering headlights, dim dashboard lights, or difficulty starting, it could be a failing alternator. CMS Auto Repair offers a comprehensive alternator diagnostic to determine if your alternator is producing enough voltage to power your vehicle and charge the battery.
We test for:
- Voltage output and charging levels
- Worn belts or pulleys
- Electrical connection issues
- Unusual noises from the alternator
