Ignition Contact Set Guide for the 1941-1950 Dodge WD15 Truck
Keep your classic Dodge truck running strong with the right ignition points.
- The ignition contact set (points) is a normal wear item that requires periodic inspection and replacement.
- Symptoms of failure include no-start, rough running, and loss of power.
- Always replace the ignition condenser at the same time as the points to ensure reliability.
- Setting the correct point gap with a feeler gauge is the most critical step for proper engine performance.
Understanding Your WD15's Ignition Points
The ignition system on your 1941-1950 Dodge WD15 is a simple and robust mechanical design. At its heart are the ignition contact set and a matching condenser, both located inside the distributor. Unlike modern electronic systems, this setup relies on the physical opening and closing of the points to time the spark for the engine. The points are designed to wear out over time and were traditionally replaced as part of a regular tune-up. Keeping them in good condition is essential for easy starting and smooth running.
Symptoms of a Failing Ignition Contact Set
When your ignition points start to wear out, your truck will usually give you clear signs. Paying attention to these symptoms can prevent you from getting stranded.
- Hard Starting or No Start: This is the most common symptom. If the points are burned, pitted, or the gap is wrong, they can't trigger the coil correctly. This results in a weak spark or no spark at all.
- Rough Running and Misfiring: Dirty or worn contact surfaces create an inconsistent spark. This can cause your engine to idle poorly, hesitate when you accelerate, or misfire.
- Engine Backfiring: A worn rubbing block on the points can change the ignition timing, which may cause the engine to backfire.
- Loss of Power: A weak or inconsistent spark leads to poor fuel combustion, which reduces your engine's power and efficiency.
Choosing the Right Aftermarket Part
For a vehicle from the 1940s, new original equipment (OEM) parts are no longer available. The market is served entirely by aftermarket manufacturers.
Available Brand: Standard Ignition
Standard Motor Products (SMP), often sold as Standard Ignition or under their premium 'Blue Streak' line, is a long-established American brand. They are a primary manufacturer of ignition components for vintage vehicles. For a part like an ignition contact set, Standard is a reliable and widely available choice. Some classic car owners feel that the quality of modern points isn't what it used to be, but Standard's Blue Streak line is often recommended as a higher-quality option. It is important to make sure you are buying the correct set for your truck's specific distributor, as there were different series used (e.g., IAO, IAP, IGS).
Pro Tip: Always Replace the Condenser
Always replace the ignition condenser when you replace the points. The condenser's job is to absorb excess electricity, preventing a large arc across the points as they open. This protects them from burning out quickly. A new condenser is inexpensive and critical for the longevity of your new points.
Estimated Replacement Costs
| Part Type | Estimated Cost |
|---|---|
| New Aftermarket Ignition Contact Set | $21.53 - $28.25 |
| Shop Labor | $100 - $180 |
| Total Professional Replacement | $121.53 - $208.25 |
Note: Costs are estimates and can vary based on location and specific repair shop rates. Many owners of classic vehicles perform this service themselves.
Frequently Asked Questions (FAQ)
What is 'point gap' and why is it important?
Point gap is the small air gap between the two contact surfaces when the points are fully open. This gap is tiny, measured in thousandths of an inch, and must be set precisely with a feeler gauge. An incorrect gap directly affects ignition timing and dwell (the amount of time the points are closed), leading to poor engine performance, hard starting, and misfiring.
How often should I replace my ignition points?
In the era when these trucks were daily drivers, points and condensers were typically replaced every 10,000-12,000 miles as part of a standard tune-up. For a classic truck that is driven less frequently, it's best to inspect the points annually for pitting or wear on the rubbing block. It's a simple and inexpensive part to replace as preventative maintenance.
Are there any recalls or bulletins for the WD15 ignition?
No. Recalls and Technical Service Bulletins (TSBs) are a modern practice. There are no active NHTSA recalls or manufacturer service bulletins for ignition components on a 1941-1950 vehicle.
Can I upgrade to electronic ignition?
Yes, electronic ignition conversion kits are available that replace the points and condenser. Owners often choose this for reduced maintenance. However, many owners prefer the simplicity and originality of the points system, which can be easily diagnosed and fixed on the side of the road with basic tools. A properly maintained points system is very reliable.
