Keep your classic Lynx's electrical system healthy by understanding how to choose the right new aftermarket alternator.
- A failing alternator will give clear signs like dimming lights, a battery warning light on the dash, or a frequently dead battery.
- No alternator-specific recalls or TSBs exist for the 1981-1987 Lynx; failures are due to normal wear and tear.
- For this vehicle, a quality new or remanufactured aftermarket alternator is a reliable and cost-effective choice.
- Replacement is a straightforward DIY job for those with basic mechanical skills, typically taking 1-2 hours.
Is it an OEM or Aftermarket Alternator?
For a vehicle like the 1981-1987 Mercury Lynx, finding a brand new Original Equipment Manufacturer (OEM) alternator from Ford is highly unlikely. Most available parts will be new or remanufactured aftermarket units. For a straightforward component like the alternator on this car, a quality aftermarket part from a reputable brand offers a practical and reliable solution without the need to search for rare, expensive new-old-stock parts.
Symptoms of a Failing Alternator
A bad alternator gives clear warning signs. Paying attention to them can prevent you from getting stuck. Your car's electrical system is simple, so problems are usually easy to spot.
- Dimming or Flickering Headlights: This is one of the most common signs. You may notice your headlights and dashboard lights are dimmer than usual, or that they flicker and change brightness as you drive.
- Battery Warning Light: Your dashboard likely has a warning light shaped like a battery or labeled "ALT" or "GEN". If this light comes on while you're driving, it's a direct signal that there's a problem with the charging system.
- Weak or Dead Battery: The alternator is supposed to recharge the battery. If your battery keeps dying and requires frequent jump-starts, the alternator is the likely culprit, not the battery itself.
- Strange Noises: A grinding or whining sound from under the hood can indicate that the bearings inside the alternator are failing. A squealing noise might point to a loose or worn drive belt.
- Slow Electrical Accessories: If your power windows move slowly or your radio acts up, it could be because the alternator isn't providing enough power.
Aftermarket Brand Quality & Cost
Choosing an aftermarket brand can be confusing. Here is a breakdown of the available brands, tiered by general reputation for this type of part. Prices for your Lynx range from approximately $27.53 to $214.70.
| Tier | Brands | General Assessment |
|---|---|---|
| Better | ACDelco, MPA | These brands are known for producing new and remanufactured parts that aim to meet or exceed original specifications. ACDelco is a well-known GM-backed brand, though some reviews can be mixed. MPA (Motorcar Parts of America) is a major supplier with a focus on quality testing. |
| Good | Remy, BBB Industries | BBB Industries is a very large remanufacturer that also owns the Remy aftermarket brand. They are a trusted supplier for many auto parts stores. Reviews are generally adequate, but some users have reported premature failures on new units. |
| Specialty | Proform | Proform specializes in performance-oriented parts, often featuring chrome finishes and higher amperage outputs. They are typically 100% new, not remanufactured, and come with individual test results. This may be a good option if you have added electrical accessories to your Lynx, but could be overkill for a stock vehicle. |
Known Issues, Recalls, and Service Bulletins
Extensive searches of the National Highway Traffic Safety Administration (NHTSA) database and other sources show no specific recalls or Technical Service Bulletins (TSBs) related to the alternator for the 1981-1987 Mercury Lynx or its twin, the Ford Escort. Any failure should be treated as a standard maintenance issue due to the age and wear of the component.
Frequently Asked Questions
Can I replace the alternator myself?
Yes. On an older vehicle like the Lynx with a simple engine layout, replacing the alternator is a very feasible DIY job for a home mechanic with basic tools. It typically involves loosening the drive belt, disconnecting the battery, removing a few bolts and electrical connectors, and then swapping the part. The estimated time is about 1-2 hours.
Should I buy a new or remanufactured alternator?
Both can be good choices. A new unit from a brand like Proform is made with all-new components. A quality remanufactured unit from a company like MPA or BBB Industries has been rebuilt to meet or exceed original standards, often with new wear items like bearings and brushes. For this vehicle, either is a suitable and reliable option when purchased from a reputable brand.
Do I need a high-output alternator?
For a stock Mercury Lynx with no major electrical upgrades, a standard output alternator is perfectly sufficient. You only need a high-output (higher amperage) alternator if you have added significant electrical loads like a powerful stereo system, extra lighting, or other accessories.
What is the most common mistake when ordering?
The most common mistake is not verifying the pulley type (V-belt vs. serpentine) and the electrical connector style. Although the 1981-1987 Lynx has a straightforward system, always compare the new part to your old one before installation to ensure the mounting points and connections match.
Technical Specifications
Externally regulated, V-belt pulley. Specific amperage varies by original equipment, but standard aftermarket replacements are sufficient for stock applications.
