GMC Canyon Alternators

Your alternator is part of your GMC Canyon pickup's charging system. It provides electricity to the parts and systems that use it. It does that by taking the engine's mechanical energy and converting it into electrical energy.

How an Alternator Works

It all starts with the crankshaft. It takes the vertical motion from the engine pistons and transforms it into rotary motion. That then moves a belt attached to a pulley located on the rotor shaft. Magnetic coils inside the shaft get agitated by the motion, producing a magnetic field that's captured as AC power by a rectifier. The rectifier changes that to the DC power that's managed by a voltage regulator and distributed to your battery, power windows, entertainment system, and other parts.

How to Spot a Failing Alternator

Even the best alternator can go bad over time, though. When that happens, your battery will quickly drain as it's become the sole source of electricity. Signs of trouble include:

• Dimming or flickering headlights
• Sound system issues
• Power windows stop working
• A whining noise coming from the engine
• A burning smell from under the hood
• The battery keeps dying

Trust Genuine GM Alternators

If you experience any of these symptoms, test your battery's voltage level with the engine turned off if you suspect your alternator is going bad. If it reads low, give it a good charge. If it's still low after that, your alternator's probably going bad. If you want to choose the right alternator for your Canyon pickup, go with one made by your manufacturer.
