Reliable Alternator Repair in Des Moines, Ankeny & West Des Moines, IA: Honest Wrenches
Your vehicle’s alternator is one of the most important components in your electrical system. It’s responsible for keeping the battery charged and powering everything from your headlights and dashboard to your radio and power windows. When the alternator starts to fail, your car won’t run properly—and eventually, it won’t run at all. At Honest Wrenches, we specialize in alternator repair in Des Moines, Ankeny, and West Des Moines, IA, offering everything from expert alternator diagnostic testing to full alternator replacement and routine alternator service.
What Does the Alternator Do?
The alternator works alongside your vehicle’s battery and charging system to keep everything running. While the battery provides the initial power to start your vehicle, the alternator takes over once the engine is running. It generates electricity and recharges the battery while powering your car’s electrical systems.
When the alternator starts to fail, it can no longer deliver consistent power. That leads to a range of electrical problems, starting issues, or even total breakdowns.
Key functions of the alternator include:
- Charging the battery
- Powering electrical accessories while the engine is running
- Regulating voltage output to avoid overcharging
- Keeping your engine and electrical systems functioning properly
If your alternator fails, the battery will quickly lose its charge, leaving your vehicle unable to start or stay running. That’s why timely alternator service is so important.
Signs You Need Alternator Repair
The alternator often gives warning signs before it fails completely. If you notice any of the following symptoms, schedule an alternator diagnostic right away:
- Dimming headlights or interior lights
- Battery warning light illuminated on the dashboard
- Electrical issues such as malfunctioning power windows or stereo
- Slow engine cranking or trouble starting
- Dead battery, even after a recent replacement
- Burning smell or unusual noises coming from the engine bay
These signs may point to alternator failure or issues with the charging system. Ignoring them could lead to a stalled engine or total loss of electrical power while driving.

Routine Alternator Service
Even if your alternator seems to be working fine, regular maintenance can help catch issues early and prevent unexpected failure. Our alternator service includes:
- Inspecting and adjusting drive belts
- Cleaning alternator connections
- Checking output voltage and current
- Evaluating system load performance
Routine checks during oil changes or general service appointments can save you time, money, and stress down the road.
What Causes Alternator Failure?
Alternators are built to last, but they can still wear out over time or fail prematurely due to:
- Worn bearings or internal components
- Loose or damaged belts
- Corrosion on wiring or terminals
- Overheating from engine issues
- Exposure to dirt, oil, or moisture
Whether your alternator is worn out from mileage or has been damaged by other engine problems, we’ll diagnose it and provide the right repair solution.
Battery or Alternator—Which One’s the Problem?
One of the most common issues we see is confusion between a dead battery and a bad alternator. The symptoms can be similar, but the repairs are very different. That’s why our alternator diagnostic service is so important.
In many cases, what seems like a battery issue is actually caused by the alternator not charging the battery properly. Replacing the battery won’t solve the problem unless the alternator is also repaired or replaced.
We’ll test both components and explain exactly what needs attention—no guessing, no unnecessary parts.
