A Comprehensive Guide to the Ignition Coil for 1950-1954 Chrysler Windsor
Keep your classic Windsor's engine firing reliably with the right new aftermarket ignition coil.
- A failing ignition coil causes symptoms like hard starting, stalling when hot, rough idle, and loss of power.
- You must use a 6-volt ignition coil for the 1950-1954 Chrysler Windsor; a 12-volt coil will not work correctly.
- Replacement is a simple, DIY-friendly task that takes less than 30 minutes with basic tools.
- For reliability, choosing a premium aftermarket brand like Standard Ignition or NGK is a wise investment.
Is Your Windsor's Ignition Coil Failing?
An ignition coil is a simple component, but it works hard. Over decades of use, the heat and vibration from the engine can cause the delicate wire windings inside to break down. This degradation leads to a weak or inconsistent spark. If your classic Chrysler is suddenly running poorly, a failing coil is a likely suspect. Watch for these common symptoms.
Choosing the Right Aftermarket Ignition Coil
For a vehicle from the early 1950s, new "OEM" parts are not a realistic option. The market consists of new aftermarket parts, which often benefit from modern manufacturing and materials that can outperform the 70-year-old original technology. Here’s a breakdown of available brand tiers to help you choose:
- Premium Brands (NGK, Standard Ignition): Brands like NGK and Standard Ignition (also known as SMP) have a long-standing reputation for producing high-quality ignition components that meet or exceed original specifications. They are trusted by professional mechanics and are an excellent choice for owners who prioritize reliability and longevity.
- Standard Brands (Spectra): Spectra is often viewed as a reliable mid-tier option. While some users have reported mixed experiences with longevity compared to premium brands, they generally offer good performance for their price point.
- Economy Brands (Global Parts): Economy-tier brands provide a functional, budget-friendly solution. While they will get your car running, their long-term durability may not match that of the more established brands.
Pro Tip: Your 1950-1954 Windsor has a 6-volt electrical system. It is critical that you purchase a 6-volt coil. Using a 12-volt coil will produce a very weak spark, while connecting a 6-volt coil to a 12-volt source can cause it to overheat and fail, sometimes bursting and leaking oil.
Estimated Replacement Costs
Replacing an ignition coil is one of the more affordable repairs for your classic Windsor. The parts themselves are not expensive, and the labor is minimal.
| Part or Service | Estimated Cost |
|---|---|
| New Aftermarket Ignition Coil | $23 - $39 |
| Shop Labor | $50 - $100 |
| Total Estimated Cost | $73 - $139 |
Frequently Asked Questions
Can I replace the ignition coil myself?
Yes, this is a very DIY-friendly job. The ignition coil is typically mounted on the engine or firewall with a single bracket. The process involves disconnecting the battery, removing two small electrical wires and the main high-tension wire to the distributor, swapping the coil, and reconnecting everything. It usually takes less than 30 minutes with basic hand tools.
Do I need a coil with a ballast resistor?
Most classic Chrysler ignition systems of this era use an external ballast resistor to protect the ignition points by reducing voltage during operation. However, some aftermarket coils are designed with internal resistance and do not require an external one. Always check the specifications of the part you are buying to ensure it matches your vehicle's setup. If you are unsure, consult a service manual for your specific year.
How do I test my old ignition coil?
You can perform a simple spark test by removing the main wire from the distributor, holding it with insulated pliers about 1/4 inch from a metal part of the engine, and having someone crank the engine. You should see a bright, blue, snapping spark. A weak, orange, or yellow spark indicates a failing coil. You can also check for physical damage like cracks or oil leaks, which are signs of internal failure.
Should I replace other ignition parts at the same time?
It's a very good idea. The ignition coil, distributor cap, rotor, condenser, points, and spark plug wires all wear out over time. Replacing them together as a set is excellent preventative maintenance and ensures your entire ignition system is refreshed for maximum reliability.
Technical Specifications
Voltage: 6-Volt. System Type: Points ignition. Check for compatibility with or without an external ballast resistor based on your vehicle's specific setup.
