Everything you need to know about replacing the ignition switch on your vintage International M Series Van.
- Symptoms often involve a no-start condition or the engine dying after the key returns to the 'Run' position.

- Standard Ignition is a reputable brand known for quality, while 'Replacement' brands are a budget-friendly alternative.
- Replacement is a simple DIY job for most owners, requiring basic tools and about an hour of time.
Is Your Ignition Switch Failing? Common Symptoms
For a vintage vehicle like the 1961-1964 International M Series Van, ignition switch problems are often due to age, wear, and corrosion. The internal contacts wear out, and connections can become loose. Watch for these signs:
- Engine Won't Crank: You turn the key to the 'Start' position and nothing happens. If the battery is good, the ignition switch may not be sending the signal to the starter solenoid.
- Starts and Immediately Stalls: The engine fires up while cranking but dies as soon as you release the key to the 'Run' position. This can happen if the switch provides power in the 'Start' position but fails to do so in the 'Run' position.
- Key is Hard to Turn or Feels Loose: The mechanical part of the switch can wear out, making the key difficult to turn or feel sloppy in the lock cylinder.
- Intermittent Power to Accessories: If your radio or gauges cut out while driving, the switch might have a loose connection internally.
- No Power at All: A completely failed switch can prevent any electrical component from turning on.
No-Start Diagnosis
Before replacing the switch, confirm your battery is fully charged and the battery cables are clean and tight. Also, check the neutral safety switch (if applicable) and the starter solenoid, as these can cause similar no-start symptoms. A common diagnostic trick is to bypass the switch with a remote starter switch connected to the solenoid; if the engine cranks, the ignition switch is a likely culprit.
Choosing the Right Aftermarket Ignition Switch
Finding a New Old Stock (NOS) OEM ignition switch for a 1960s International van is nearly impossible. Used switches from salvage yards are an option, but they carry the same risks of age and wear as your old part. For reliability, a new aftermarket switch is the best choice. Two main brands are available:
Brand Tiers
- Standard Ignition (Standard Motor Products): A well-regarded aftermarket manufacturer that has been around for over 100 years. Their switches, like the common US14 model, are often built with copper alloy conductors for better conductivity and are tested for proper function. This is a trusted choice for owners looking for quality and durability.
- Replacement: This is typically a generic or store-brand option. These switches are designed to meet basic fit and function requirements at a lower price point. While they will get your van running, they may not have the same long-term durability or material quality as a branded part like Standard Ignition.
For a critical part like the ignition switch, spending a little more on a reputable brand like Standard Ignition can prevent future headaches and ensure your vintage van starts reliably every time.
