Essential Guide to the 1953-1954 Hudson Super Jet Ignition Coil
Keep your classic Hudson's engine firing on all cylinders with the correct replacement ignition coil.
- You must buy a 6-volt ignition coil; a 12-volt coil will not work correctly.
- Symptoms often get worse as the engine heats up.
- Standard Ignition (SMP) is generally considered a more reliable brand than Spectra for this part.
- Replacement is a simple DIY task that takes less than 30 minutes.
Is Your Hudson Super Jet's Ignition Coil Failing?
An ignition coil on a classic car like the 1953-1954 Super Jet can fail gradually. A common sign of a failing coil is when the engine runs well when it's cold but begins to sputter, misfire, or stall after it warms up. Because these cars are over 70 years old, an original coil is well past its expected service life. If you're experiencing engine trouble, the coil is a prime suspect.
Critical System Note: 6-Volt System
Your 1953-1954 Hudson Super Jet uses a 6-volt electrical system. You must use an ignition coil specifically designed for a 6-volt system. Using a 12-volt coil will produce a very weak spark, while using a 12-volt battery with a 6-volt coil without a proper ballast resistor can cause the coil to overheat and fail, sometimes bursting and leaking oil.
Choosing the Right Aftermarket Coil
Original factory-installed ignition coils for your Hudson are no longer manufactured. Your only practical option is a new aftermarket part. Fortunately, modern manufacturing provides reliable replacements. The two main brands you will find are Standard Ignition and Spectra.
Brand Quality Tiers
- Standard Ignition (Standard Motor Products): Generally considered a top-tier aftermarket brand with a long history of making quality ignition parts for American vehicles. Many professional mechanics and restorers trust SMP for its reliability and performance, which often meets or exceeds original specifications. For a critical component on a classic car, this is often the preferred choice.
- Spectra (Spectra Premium): Spectra is a value-oriented brand. While some users report good experiences, others have noted a higher rate of failure with their ignition components compared to brands like Standard. Given the relatively small price difference, most owners of classic vehicles opt for the more established reliability of Standard Ignition.
Pro Tip: Consider a Tune-Up
While you are replacing the ignition coil, it is a great time to inspect or replace other tune-up parts in the ignition system. This includes the spark plugs, spark plug wires, distributor cap, rotor, points, and condenser. These parts work together, and a fresh set will ensure your engine runs its best.
Estimated Costs for a New Ignition Coil
| Part Type | Estimated Cost |
|---|---|
| New Aftermarket (Spectra, Standard) | $28 - $39 |
| New OEM | Not Available |
| Used OEM | Varies (Specialty Suppliers) |
| Shop Labor | $50 - $100 |
Frequently Asked Questions (FAQ)
How do I test my Hudson's ignition coil?
You can perform two basic tests with a multimeter. For the primary resistance, disconnect the small wires and measure between the '+' and '-' terminals; you should see about 1.0 to 2.0 ohms. For the secondary resistance, measure from a primary terminal to the center high-voltage tower; you should see 6,000 to 10,000 ohms. A more practical test is to check for a bright, blue spark from the main coil wire held near a ground on the engine block while a helper cranks the engine. A weak, yellow or orange spark indicates a bad coil.
Do I need a ballast resistor with my new coil?
No, if you are using the correct 6-volt coil on your Super Jet's original 6-volt system, you do not need an external ballast resistor. These coils are designed to run directly on 6 volts.
Is replacing the ignition coil a difficult job?
No, this is a very easy job for a DIY mechanic. The coil is typically mounted to the engine or firewall with a simple bracket. It involves disconnecting the battery, removing two small primary wires, pulling off the main high-tension wire that goes to the distributor, and unbolting the bracket. Installation is the reverse of removal.
What are common mistakes when ordering this part?
The most common mistake is ordering a 12-volt coil. You must ensure the part is specified for a 6-volt system. Also, check if the new coil comes with a mounting bracket. Some do not, and you will need to reuse your original one.
