Ignition Contact Set Guide for the 1966 Studebaker Wagonaire
Solve hard starting and rough running issues by understanding and replacing the ignition points in your classic Wagonaire.
- The ignition contact set (points) is a regular maintenance item on a 1966 Wagonaire and should be replaced about every 12,000 miles or annually.
- Common failure symptoms include hard starting, rough idle, misfires, and reduced power.
- Always replace the condenser at the same time as the points to ensure the longevity of the new parts.
- Setting the correct point gap is critical for performance; for the Studebaker V8, the gap is typically 0.016 inches.
Understanding Ignition Point Failure in Your Wagonaire
For owners of a 1966 Studebaker Wagonaire, the ignition contact set is a key part of the original ignition system. These are not complex parts, but they are a wear-and-tear item that needs regular attention, much like spark plugs or oil. Over time, the constant opening and closing, along with the electrical current, cause the contact surfaces to burn, pit, and wear down. Additionally, the small rubbing block that rides on the distributor cam wears out, which changes the point gap and directly affects engine timing and performance. When these components wear, it leads to a range of engine problems that can worsen over time and eventually prevent the engine from starting.
Common Symptoms of Failing Ignition Points
- Hard Starting or No Start: Worn or pitted points cannot create a clean electrical break, resulting in a weak or nonexistent spark. This is often the most common first sign of failure.
- Engine Misfires and Rough Idle: Inconsistent contact leads to an erratic spark, causing cylinders to misfire. This makes the engine shake, idle poorly, and hesitate during acceleration.
- Stalling: At low RPMs, like at a stoplight, the inconsistent spark from bad points can be enough to cause the engine to stall completely.
- Reduced Power: When the points are worn, ignition timing is no longer optimal. This means the spark happens at the wrong moment, reducing engine power and fuel efficiency.
A Note on Distributor Shaft Wear
A lesser-known issue on high-mileage classic cars is wear in the distributor shaft bushings. This can cause the shaft to wobble, leading to an inconsistent point gap even with a new set of points. If you set the gap correctly but symptoms persist, check for side-to-side play in the distributor shaft. This may indicate the distributor needs to be rebuilt or replaced.
Choosing the Right Aftermarket Ignition Contact Set
For a 1966 Studebaker, finding original factory (OEM) parts is nearly impossible. The market primarily consists of New Old Stock (NOS) parts and modern aftermarket reproductions. While NOS parts are 'original', they may have degraded over 60+ years of storage, especially the condenser. Modern aftermarket parts from a reputable brand are often the most reliable choice.
Standard Ignition (Standard Motor Products): This is a long-standing and widely available brand for classic car ignition components. Their parts are manufactured to meet the original specifications and are considered a reliable standard for keeping these vehicles on the road. When purchasing a contact set, it is highly recommended to get a kit that includes a new condenser.

Frequently Asked Questions (FAQ)
What exactly are ignition points?
Ignition points are a mechanical switch that controls the timing of the spark in your engine. They consist of two contacts that are opened and closed by a spinning lobe on the distributor shaft. This action triggers the ignition coil.
How often should I replace the ignition points?
As a standard maintenance item, ignition points should be inspected at every tune-up and typically replaced every 10,000 to 12,000 miles, or at least once a year. Regular inspection can help you spot wear before it becomes a major problem.
What tools do I need to replace ignition points?
You will need basic hand tools like a screwdriver and wrenches to open the distributor cap. The most important special tool is a feeler gauge to set the correct gap on the new points. A dwell meter provides a more accurate adjustment but is not strictly necessary.
What is the correct point gap for my Wagonaire?
For Studebaker V8 engines (259ci, 289ci), the point gap is typically set to 0.016 inches. For the 6-cylinder engines, the gap is usually 0.020 inches. The dwell angle, a more precise measurement, should be 28-32 degrees for the V8. Always confirm the specification for your specific engine and distributor.
Why must I replace the condenser with the points?
The condenser is a small capacitor that absorbs a surge of electricity when the points open. This prevents a large spark from jumping across the points themselves, which would cause them to burn and fail very quickly. A faulty condenser will ruin a new set of points, so they should always be replaced together as a set.
