A Guide to the Ignition Contact Set for the 1942 Packard 20th Series
Keep your classic Packard's ignition system reliable with the right set of points.
- Symptoms like hard starting, rough idle, and stalling are strong indicators of a failing ignition contact set.
- For a 1942 Packard, a new aftermarket set from a known brand like Standard Ignition is a reliable choice.
- Always replace the condenser at the same time as the points for long-term reliability.
- No official recalls or TSBs exist for this part on this vehicle; failures are due to normal wear.
Is Your 1942 Packard Showing Signs of a Bad Ignition Contact Set?
The ignition contact set is a critical wear-and-tear part in your Packard's ignition system. When the points wear down, get dirty, or become misaligned, they can cause noticeable running problems. Because these parts control the engine's spark, a failure can leave you stranded. Recognizing the symptoms early can save you from a breakdown.
Common Failure Symptoms
- Engine Won't Start: The most common symptom is an engine that cranks but refuses to start. This happens when the points are too worn or damaged to create a proper electrical signal for the coil.
- Rough Idle and Misfiring: Worn or pitted points can't deliver a consistent spark, leading to an engine that shakes, stutters, or runs unevenly.
- Stalling: The engine may stall unexpectedly, especially at idle or when you come to a stop. This can be a safety hazard in traffic.
- Poor Acceleration: If your Packard feels sluggish or hesitates when you press the gas pedal, it may be due to a weak or intermittent spark from failing points.
Choosing the Right Aftermarket Part
For a 1942 vehicle, original Packard parts are no longer manufactured. Your options are typically New Old Stock (NOS) or new aftermarket reproductions. While NOS parts sound appealing, components like condensers can degrade over many decades in storage. A new, quality aftermarket part is often the most reliable choice for a car you intend to drive.
Available Brand: Standard Ignition
Standard Motor Products (SMP) has been a major manufacturer of ignition parts for decades. For classic American vehicles, their parts are generally considered a quality option. Their premium "Blue Streak" line is noted for higher quality. While some classic car enthusiasts feel modern points don't last as long as originals from the 1960s, a new set from Standard Ignition is a dependable choice that will perform correctly when installed properly. It is always recommended to replace the condenser at the same time as the points.

Known Issues for the 1942 Packard
There are no recalls or specific Technical Service Bulletins (TSBs) from the manufacturer for the ignition system on a 1942 Packard. The National Highway Traffic Safety Administration (NHTSA), which manages modern recalls, was not established until 1970. Any issues with the points are typically due to normal wear and tear over time. A common issue on any older engine with points is accelerated wear of the rubbing block if the distributor cam is not properly lubricated during installation.
Frequently Asked Questions (FAQ)
How often should ignition points be replaced?
As a routine maintenance item, points and condensers were typically replaced every 10,000 to 20,000 miles. For a classic car that is driven less frequently, they should be inspected annually for pitting, burning, or excessive wear on the rubbing block.
Can I replace the ignition contact set myself?
Yes, this is a common DIY job for those with experience working on vintage cars. It requires basic hand tools, a feeler gauge to set the point gap, and a bit of patience. If you are not comfortable working inside the distributor, a mechanic familiar with classic cars can perform the service quickly.
What is a "point gap" and why is it important?
The point gap is the small distance the contacts open. This gap is critical for correct ignition timing and coil charging. If the gap is too small or too large, it will cause poor running, misfires, and hard starting. The correct specification for your Packard should be followed for best performance.
Should I convert to an electronic ignition?
Many owners of classic cars choose to replace the points and condenser with an electronic ignition conversion kit. These kits eliminate the need for regular adjustment and can provide a more consistent spark. However, a properly maintained original-style points system is very reliable. Some electronic systems can also fail without warning, whereas points usually give signs of wear before they stop working completely.
