Your truck’s ability to run is dependent on electricity powering its battery in the right amount. The alternator of your truck delivers this electricity to the electrical system of your truck, which includes the battery. When the alternator is failing, the battery won’t be properly powered, and you may not be able to start your vehicle.
Here are three of the most common culprits behind failing truck alternators.
- Improper Connection. Like in other vehicles, truck alternators are connected to a system of wires and other components that deliver electricity to the battery and other parts. If your alternator has been improperly connected, the alternator won’t charge properly, which can lead to overcharging.
- Dying Bearings. Part of your truck’s alternator is the bearings, which play a role in reducing friction within your alternator. Over time, these bearings will get worn down and “die,” leading to alternator issues.
- Time. Maintaining your truck’s electrical system will help extend the lifespan of its alternator as well as the other moving parts in your vehicle, but eventually, your alternator will break down. This is normal, as no mechanical part will last forever. Truck alternators can last upwards of seven years, so if your alternator hasn’t been replaced in over seven years, chances are you’ll be looking at a replacement service soon.
Recognizing the signs of a failing alternator can help prevent you from getting stranded in the event that your alternator dies completely before you’re able to get it replaced. These signs include a burning rubber odor while driving, dim lights (both headlights and interior lights), and problems starting your truck even with a newer battery.
