Battery, Starter & Alternator Repair in Calgary SE & SW

Is your vehicle slow to crank, completely dead, or showing a battery/charging warning light on the dash? If your car won’t start—or starts sometimes and not others—your starting and charging system may need attention. The battery, starter, alternator, cables, and related wiring all work together to start your engine and keep power flowing while you drive. When one part fails, you can end up stranded at the worst time.

At Heritage AutoPro, we provide accurate battery testing, alternator testing, and starter diagnostics in Calgary SE & SW for most makes and models. We don’t just swap parts—we test first, explain what we find, and repair only what’s actually needed.

Common Symptoms of Starting & Charging Problems

You may have a battery, starter, or alternator issue if you notice:

• No crank / no start (nothing happens when turning the key)

• Slow cranking or clicking sound

• Vehicle starts after a boost but dies again later

• Lights dimming or electrical glitches (radio, dash, power windows)

• Burning smell or hot battery cables

What We Check During Diagnosis

To pinpoint the real cause, our technicians may perform:

• Battery health test and charging system performance test

• Starter draw/operation checks (where applicable)

• Alternator output and charging control checks

• Visual inspection of battery terminals, cables, and grounds

• Testing for parasitic draw (battery drain) when needed

• Checks on computer-controlled charging systems and related circuits

• Anti-theft / immobilizer-related starting checks when applicable

You’ll get clear answers: Is it the battery? starter? alternator? wiring? or a drain?
