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

Driving an RV from SC through TN on a Sunday. Called the big company near Specialized Trucking to jump our generator. Wouldn’t help us. I called Specialized Trucking helped us while extremely busy got our generator jumped in less than 10 minutes. Rock star service. Thank you SO much!!!
These guys are absolutely AMAZING!!!! I had an issue with my trailer and they went above and beyond anything I could've asked for to ensure that I was back on the road!!!! I have never had customer service this awesome from anywhere else!!!
This place was a great place to get a repair, they were very nice and fast and professional and it was very cost efficient. Highly recommend giving this shop a try! Stephon really knew what he was doing. Awesome Job!!
Had brakes repaired on my 2012 Expedition. Completely satisfied. Owner is honest and makes a great effort to see that each repair is to done correctly and that the customer is satisfied. Brant Jones has been my mechanic for 18 years. An honest and helpful mechanic is a good find. Any one star reviews are most likely written by someone who cannot be pleased or by a competing auto repair shop.
They got my truck in quickly and fixed the issue. Edgar was very knowledgeable and helpful.
We had an emissions problem on our Peterbilt. The tech was professional and courteous. I recommend these guys to anyone needing expertise
The team were fantastic. They came to our location where our truck was disabled several blocks from their business, they got under the hood and quickly and correctly diagnosed an obscure broken part in our power steering assembly, ordered the part and had it installed the next week, and did the entire thing so affordably we couldn’t believe we were in Nashville. 10 stars if possible.
I’m very pleased with repair on my RV. When no one else would even schedule me they worked me in and replaced the fuel pump in my tank. Very pleased!
