Ignition Coil Guide for the 1950-1956 Nash Statesman
Keep your classic Nash running strong by understanding its unique ignition coil needs.
- Verify your car has its original 6-volt system before ordering a new coil.
- A no-start, stalling, or rough running engine are classic signs of a failing ignition coil.
- Standard Ignition (SMP) is generally a more reputable aftermarket choice than budget brands.
- Replacement is a simple DIY job that takes less than 30 minutes with basic tools.
Is Your Nash Statesman's Ignition Coil Failing?
An ignition coil is a wear-and-tear part. Heat and vibration are its main enemies, causing the delicate wire windings inside to break down over time. When the coil starts to go bad, it can't produce a consistently strong spark, leading to noticeable engine problems. Eventually, it will fail completely, leaving you stranded.
Common Symptoms of a Bad Coil:
- Hard Starting or No-Start: The engine cranks but won't fire up, or takes a very long time to start. This happens because the spark is too weak to ignite the fuel.
- Engine Misfires or Rough Idle: The engine shakes, sputters, or runs unevenly, especially when stopped. This can feel like a constant stumble or vibration.
- Stalling: The engine may suddenly cut out while driving or when coming to a stop. This can happen without warning when the coil gets hot and fails intermittently.
- Backfiring: Loud popping sounds from the exhaust can occur when unburned fuel enters the exhaust system and ignites.
- Loss of Power: The car feels sluggish and doesn't accelerate as it should. This is a result of incomplete combustion in the cylinders.
A Note on Your 6-Volt System
Your 1950-1956 Nash Statesman originally came with a 6-volt electrical system. It is critical to use an ignition coil designed specifically for a 6-volt system. Using a 12-volt coil will result in a very weak spark and poor performance. Always confirm you are buying a 6-volt coil. Some cars from this era have been converted to 12-volt systems, so it's wise to double-check your car's setup if you are not the original owner.
Choosing the Right Aftermarket Ignition Coil
For a vehicle of this age, new original equipment (OEM) parts are no longer made. Your choices are New Old Stock (NOS) parts, which are rare and expensive, or new aftermarket parts. Aftermarket coils are a reliable and affordable choice for keeping your classic on the road.
Available Brands: Spectra vs. Standard Ignition
Two common brands you'll find for your Statesman are Spectra and Standard Ignition (often called SMP).
- Standard Ignition (SMP): Generally considered a reliable aftermarket brand with a long history. Many mechanics trust SMP for ignition components that meet original design specifications. While some reviews mention occasional quality issues with their economy lines (T-Series), their main line is a solid choice for dependability.
- Spectra: Often positioned as a budget-friendly option. Reviews can be mixed; some users report success, while others have experienced premature failures, suggesting quality can be inconsistent. If choosing Spectra, be aware that it may not have the same longevity as a more established brand.
Pro Tip: When replacing your ignition coil, it's also a good time to inspect or replace the ignition points, condenser, spark plugs, and spark plug wires. These parts all work together, and a new coil will perform best with a full tune-up.

Frequently Asked Questions
How do I know if I have a 6-volt or 12-volt system?
The easiest way is to check the battery. A 6-volt battery will have 3 filler caps on top, while a 12-volt battery will have 6. Unless your car has been specifically converted by a previous owner, it should be a 6-volt system.
Do I need a coil with an external ballast resistor?
Most original 6-volt systems of this era do not use a ballast resistor. You should use a coil that is internally resisted and designed for a 6-volt system without a resistor. Using the wrong type can cause the ignition points to burn out quickly or result in a weak spark.
How can I test my old ignition coil?
A simple test involves checking for spark. Remove the main wire from the center of the distributor cap, hold the metal end about 1/4 inch from a metal part of the engine, and have someone crank the engine. You should see a bright blue spark. A weak, yellow spark or no spark at all points to a bad coil. For a more precise test, you can use a multimeter to check the resistance of the primary and secondary windings, though this is more advanced.
Is replacing the ignition coil a difficult job?
No, this is a very straightforward job for a DIY mechanic. It involves disconnecting the battery, removing a few low-voltage wires and the main high-tension wire, and unbolting the coil from its mounting bracket. The entire process usually takes less than 30 minutes.
