Top Signs You Need a New Alternator or Starter in Malden, MA
Don’t Get Stranded — Know the Warning Signs Before It’s Too Late
At Hub Starters in Malden, MA, we’ve seen it time and time again — a customer comes in with a car that won’t start, only to discover the alternator or starter was failing long before it completely died. The truth is, your vehicle does give you warning signs when something is wrong. The trick is knowing what to look for.
In this post, we’ll break down the top signs that your alternator or starter may need replacement — and what to do if you notice them.
What Does the Alternator Do?
Your alternator powers all your car’s electrical systems while the engine is running. It keeps the battery charged and ensures your lights, radio, and other electronics work properly.
Common Alternator Issues:
- Worn bearings or voltage regulators
- Bad diodes
- Loose belts or corroded wires
What Does the Starter Do?
The starter is a small motor that gets your engine turning when you turn the key (or press the start button). Without it, your engine won’t start — plain and simple.
Top Warning Signs of a Failing Alternator
1. Dimming or Flickering Headlights
If your lights get dimmer while idling or brighter when revving the engine, your alternator may not be delivering consistent voltage.
2. Battery Warning Light
The battery light on your dashboard can actually indicate a problem with the alternator, not the battery itself. Don’t ignore this red flag!
3. Dead Battery
If your battery is new but keeps dying, your alternator may not be recharging it.
4. Electrical Failures
Power windows sluggish? Radio cutting out? Dashboard lights acting strange? That’s often a sign of voltage problems — usually from the alternator.
5. Burning Smell
Overheating alternators often emit a faint burning rubber or wire smell due to a slipping belt or internal failure.
Top Warning Signs of a Failing Starter
1. Clicking Noise When You Turn the Key
Hear a single “click” and nothing else? That’s a classic sign the starter solenoid is trying — but failing — to engage.
2. Engine Won’t Crank
If you get power to your dashboard but the engine doesn’t turn over, the starter could be worn out.
3. Grinding Noise
This could mean the starter gear isn’t properly engaging with the flywheel — a serious issue that can cause damage if left unchecked.
4. Smoke from Under the Hood
Overheating starters can produce smoke or a burning smell. This is urgent — turn off the car and call a pro.
