Chrysler New Yorker Voltage Regulator Guide (1966-1982)
Keep your classic Chrysler's charging system reliable by understanding and diagnosing your voltage regulator.
- A failing voltage regulator causes issues like flickering lights, a dead battery, and erratic gauge readings.
- Upgrading from an original mechanical regulator to a modern electronic one is a smart choice for reliability.
- Ensure the new regulator has a clean, tight ground connection to the firewall; this is a common point of failure.
- Standard Ignition is a reputable aftermarket brand offering reliable electronic replacements for this vehicle.
Understanding Your New Yorker's Voltage Regulator
For the 1966-1982 Chrysler New Yorker, the voltage regulator is a critical component that has seen some changes over the years. Early models in this period used a mechanical, points-style regulator. These are known to wear out over time. Later models, and most modern aftermarket replacements, use solid-state electronic designs for improved reliability and more precise voltage control. A failing regulator can cause a host of electrical gremlins that might not seem related at first, but they all trace back to unstable voltage in your car's system.
Symptoms of a Failing Voltage Regulator
A bad voltage regulator can show itself in several ways. Because it controls the charging system's output, symptoms often involve either too much or too little power.
- Lighting Issues: Your headlights and dashboard lights might flicker, appear unusually dim, or be excessively bright. An overcharging situation can cause bulbs to burn out frequently.
- Battery Problems: A constantly dead battery is a common sign. The regulator might not be letting the alternator charge the battery enough. Conversely, an overcharging regulator can boil the acid in the battery, causing permanent damage.
- Erratic Ammeter Gauge: The factory ammeter on your dashboard may swing wildly, stay pegged on the 'Charge' side, or always show a 'Discharge'. This is a classic symptom in Mopars of this era.
- Engine Stalling: Unstable voltage can sometimes affect the ignition system, leading to poor performance or stalling.
A Note on Mopar Charging Systems
The charging systems in 1960s and 70s Chrysler vehicles have known weak points. A failing voltage regulator can cause overcharging, which can overheat and melt the main bulkhead connector on the firewall. It's also important to ensure the regulator has a clean, tight ground connection to the chassis, as a bad ground is a common cause of failure.
Choosing the Right Aftermarket Regulator
Today, finding a new old stock (NOS) Mopar mechanical regulator is difficult, and quality can be questionable. Aftermarket electronic regulators are the most common and reliable choice for these vehicles. They offer the benefit of modern, solid-state technology in a package that often bolts right in.
Standard Ignition (Standard Motor Products):
Standard is a well-regarded aftermarket manufacturer that has been around for a long time and even supplies parts to vehicle manufacturers. Their parts are generally considered to be of good quality, often meeting or exceeding original specifications. For classic vehicles like the New Yorker, their electronic replacement regulators are a popular choice. They provide the reliability of a modern part, which is a significant upgrade over the original mechanical design. Some owners have noted that the quality of even reputable aftermarket parts can vary, but Standard is generally seen as a dependable option.
Pro Tip: Electronic Upgrade
If your pre-1970 New Yorker still has its original mechanical regulator, switching to a modern electronic replacement from a brand like Standard is a highly recommended upgrade for reliability and performance. Many are designed as direct-fit replacements, requiring no modifications.

Frequently Asked Questions
Is it difficult to replace a voltage regulator on my New Yorker?
No, this is a very DIY-friendly job. The regulator is typically mounted externally on the firewall or inner fender. It involves disconnecting the battery, unplugging one electrical connector, and removing two or three mounting screws. The entire process usually takes less than 30 minutes.
My new regulator isn't working. What should I check?
First, ensure the regulator has a clean, solid ground. The mounting screws provide the ground path, so the area on the firewall must be bare metal. Also, check the wiring connector for corrosion. If these are good, the issue might be with the alternator or other wiring in the charging system.
Should I get a mechanical or electronic voltage regulator?
For a vehicle that is driven regularly, an electronic regulator is the superior choice. It provides more stable voltage, is more durable, and has a longer lifespan than the original mechanical points-style regulators. Aftermarket brands like Standard Ignition offer direct-fit electronic versions.
Can a bad voltage regulator damage my alternator?
While a bad regulator is more likely to damage the battery by overcharging or undercharging it, the components of the charging system are all related. An overcharging condition puts stress on the entire electrical system. It's best to address a faulty regulator promptly to avoid cascading problems.
Technical Specifications
Externally mounted, 12-volt system. Early models used a mechanical (points-type) regulator, while later models and all modern replacements are solid-state electronic. The regulator is grounded through its mounting screws to the vehicle body.
