Electrical System Services

The health of your electrical system is vital to your vehicle's basic functioning and performance. When you bring your vehicle to St J Auto for this service, we will inspect your battery, starter, alternator, and ignition to ensure they are properly maintained and make repairs and replacements when necessary.

Alternator Inspection & Repair Service


The alternator charges the battery and sends power to your vehicle's electrical system when the engine is not running. We can measure the voltage produced and repair or replace the alternator if necessary.

Battery Testing, Repair & Replacement Service

Testing the battery allows for early detection of problems so it can be replaced before finding yourself stranded with a dead battery. If problems are detected, the battery may be replaced with a new model according to your vehicle manufacturer's specification.

Ignition Inspection & Repair Service

Your vehicle's ignition creates the spark that ignites the fuel/air mixture in the engine. We can check the proper functioning of each part and repair or replace any parts if necessary.

Interior & Exterior Light Inspection & Replacement Service

When we perform this service, we check all interior lights, exterior headlights, brake lights, blinkers and make replacements when necessary.
