Overview of Heavy-Duty Truck Alternators

The starting system and the charging system make up the bulk of the electrical system. Important components are batteries, the starter, the alternator, interconnecting wiring, and electrical relays. If your alternator isn't functioning properly, it can actually effect your truck's overall efficiency and be fairly costly over long hauls, leading to increased fuel costs and possible downtime.

Do I need to replace my alternator?

Is it a dead battery or a failing alternator? Here's a quick checklist to diagnose which it might be:

Dying battery

If your alternator's not running properly, your truck will drain your battery reserves and stop powering lights, starting, or other issues. If you're going to replace a battery, check the alternator first to make sure it's delivering adequate current.

Lights are dim

Dim and/or flickering lights are one of the most commons signs of a failing alternator. It might be a sudden burst of light coming from your headlights or simply a dim or flickering dashboard. Either way, this is a telltale sign that your alternator needs service.

Electrical problems

Is your radio turning off out of nowhere? Or maybe your phone isn't charging? Or maybe your power seats feel like they're taking forever to adjust. This shows a lack of electrical power and could likely be the result of your alternator or batteries not functioning properly.

Stalling engine

If you're calling for emergency roadside service with this one, your in the right place. Your alternator might be the issue if your engine suddenly cuts power while hauling. It's likely the result of the vehicle no longer providing enough power to the ECM, which will shut down around 9.6v.

Service engine light

Don't be the guy who ignores the "Check Engine" or "ALT" light. An ounce of prevention is worth a pound of cure when it comes to your truck. Note that your dashboard might show a battery icon even when the alternator is the issue.

Squealing, Growling or Grinding Sounds

The serpentine belt is going to stretch over time. As it stretches, it stops spinning the alternator pulley properly and it results in a lack of charge. You'll notice this when a squealing, growling, or grinding sound is coming from the engine.

This place is as shady as it gets. They promised to replace my trailor tires at a better cost than everyone else. Turns out I learned the hard way about tires. They replaced my radial tires with nylon bi tires. Brand new tires were getting so hot that they would split in half and shred apart while driving only an hour on them. They said they couldn't help me and gave me a check for a fraction of what I spent with them. Paul is very untrustworthy and does not treat there customers well. Warning, beware of them and if your in a bind and have to use them, make sure your getting what they promise. I'll also be reviewing them on the BBB and letting everyone I know to steer clear!This place is as shady as it gets. They promised to replace my trailor tires at a better cost than everyone else.

Went there for force regen and the front desk employee asked me to wait in truck . After waiting for 2 hours went back to office and she said we thought you left and we can’t repair your truck today . Wasted my time . Its better go to 10-4 truck service and also their price is resonable.
