Guide to the 1956 Studebaker E7 Starter Solenoid
Understanding how to diagnose and replace the starter solenoid on your classic Studebaker truck.
- A single loud 'click' with no engine crank is the most common symptom of a failed starter solenoid on a 1956 Studebaker E7.
- For this classic truck, a new aftermarket solenoid from a reputable brand like Standard Ignition is the most practical and reliable replacement option.
- Verify whether your truck has a 6-volt or 12-volt electrical system before purchasing a new solenoid to ensure compatibility.
- Replacing the solenoid is a simple, low-cost job that most owners can perform themselves with basic tools in under an hour.
Is Your Studebaker E7 Failing to Start? It Could Be the Starter Solenoid.
For owners of a classic 1956 Studebaker E7, a no-start condition can be frustrating. Often, the battery and starter motor are blamed, but the small starter solenoid is a common point of failure. This component is responsible for handling the high amperage required by the starter motor. Due to age, heat, and thousands of starting cycles, the internal contacts can wear out or corrode, leading to starting problems.
Common Failure Symptoms
- Single Loud Click: You turn the key and hear one loud "click" from the engine bay, but the engine doesn't crank. This usually means the solenoid is engaging but failing to pass power to the starter.
- No Sound at All: If there's no click and no crank, the solenoid might have failed completely and isn't activating at all.
- Intermittent Starting: The truck starts fine one day but only clicks the next. This suggests the solenoid's internal contacts are worn and only making a connection sometimes.
- Starter Keeps Running: In rare cases, the solenoid's internal switch can get stuck in the 'on' position, causing the starter to continue running even after the engine has started. This can cause serious damage to the starter.
Choosing the Right Aftermarket Solenoid
For a vehicle as old as a 1956 Studebaker, finding "New Old Stock" (NOS) OEM parts is extremely difficult and often very expensive. The most practical and reliable option is a new aftermarket part. Aftermarket brands have been producing replacement parts for classic vehicles for decades.
Standard Motor Products (Standard Ignition):
Standard Ignition is a well-known and long-standing brand in the automotive aftermarket. For many classic vehicles like the Studebaker E7, they are one of the primary, if not only, sources for new electrical components. Reviews for their solenoids are generally positive, with customers noting they are a good replacement for original parts. While some enthusiasts express concern over modern manufacturing quality compared to old OEM parts, a new Standard solenoid is widely considered a reliable choice and a significant improvement over a failing original part.
A Note on 6-Volt Systems
Some earlier and base model Studebaker trucks used a 6-volt electrical system. It is crucial to verify if your truck is a 6-volt or 12-volt system before ordering. Installing a 12-volt solenoid on a 6-volt system (or vice-versa) will lead to immediate failure or poor performance. The E7 series could have different configurations, so always check your specific truck's setup.
Estimated Replacement Costs
The cost to replace a starter solenoid on a 1956 Studebaker E7 is relatively low, especially if you can do the work yourself. The part itself is affordable, and the job is straightforward on these classic trucks.
| Part/Service | Estimated Cost |
|---|---|
| New Aftermarket Solenoid (Standard Ignition) | $49.14 |
| Shop Labor | $60 - $120 |
| Total Estimated Cost | $109 - $170 |
Frequently Asked Questions (FAQ)
Can I replace the starter solenoid myself?
Yes, for most owners with basic hand tools, this is a very feasible DIY job. On the E7, the solenoid is typically mounted in an accessible location on the firewall or inner fender. The process involves disconnecting the battery, carefully noting the wire locations, unbolting the old solenoid, and installing the new one in its place.
Is a clicking sound always a bad solenoid?
A single, loud click strongly points to the solenoid. However, a rapid series of clicks (like a machine gun) often indicates a low or dead battery that doesn't have enough power to turn the starter motor. Always make sure your battery is fully charged and the terminals are clean before replacing the solenoid.
Where is the starter solenoid located on my 1956 E7?
On classic trucks from this era, the solenoid is usually not attached to the starter. Look for a small, cylindrical component mounted on the firewall (the metal wall between the engine and the cab) or the inner fender panel. It will have the thick, positive battery cable connected to one of its large posts.
Are there any recalls or bulletins for the Studebaker E7 starter solenoid?
No, due to the age of the vehicle, there are no active NHTSA recalls or manufacturer Technical Service Bulletins (TSBs) for the starter solenoid on a 1956 Studebaker E7. Any issues are addressed through standard diagnosis and repair.
