Starter Solenoid Guide for the 1956-1958 Studebaker President
Troubleshoot starting problems and choose the right replacement starter solenoid for your classic Studebaker.
- The most common symptom of failure is a single loud click when you turn the key, with no engine crank.
- For this vehicle, the solenoid is likely a separate part on the firewall or fender, making it an easy DIY replacement.
- New aftermarket solenoids from brands like Standard Ignition are the most practical and reliable choice.
- Always check your battery, cables, and ground connections before replacing the solenoid, as these are common issues on classic cars.
Is Your Studebaker President Having Trouble Starting?
A reliable start is essential for enjoying your classic Studebaker. If you're turning the key and only hearing a click, or nothing at all, a faulty starter solenoid could be the culprit. This component is a common failure point due to age and the high electrical loads it handles. Understanding its symptoms can help you diagnose the problem correctly and get your President back on the road.
Common Symptoms of a Failing Starter Solenoid
Because the starting system is simple on these vehicles, diagnosing a bad solenoid is often straightforward. Look out for these common signs:
- Single, Loud Click: You turn the key and hear one distinct click from the engine bay, but the engine doesn't crank. This often means the solenoid is receiving power but failing to send it to the starter motor.
- No Sound at All: If there's no click and no cranking, the solenoid might have failed completely, creating an open circuit. Always check your battery and cables first to rule out a simple power issue.
- Intermittent Starting: The car starts fine on some attempts but fails on others. This can be caused by worn or dirty internal contacts inside the solenoid.
- Starter Keeps Running: After the engine starts and you release the key, the starter motor continues to run. This indicates the solenoid's internal switch is stuck in the closed position, which can quickly damage the starter.
Important: Check the Basics First
Before blaming the solenoid, ensure your battery is fully charged and the battery terminals and cables are clean and tight. On a classic car, poor grounds and corroded connections are common sources of starting problems.
Choosing a New Aftermarket Solenoid
For a vehicle from the 1950s, finding "new old stock" (NOS) OEM parts can be difficult and expensive. Aftermarket parts are the most practical and widely available option.
Standard Ignition (Standard Motor Products): This is a well-known aftermarket brand that produces a wide range of electrical components. Their solenoids are designed to meet or exceed original specifications. They typically feature heavy-duty copper contacts and strong windings to ensure reliable performance and a long service life, which is crucial for handling the electrical demands of a V8 engine.
Known Issues, Recalls, or Service Bulletins
There are no active recalls or Technical Service Bulletins (TSBs) on file with the National Highway Traffic Safety Administration (NHTSA) for the starter solenoid on the 1956-1958 Studebaker President. This is expected for a vehicle of this era, as modern digital records were not kept. Any original service bulletins would have been distributed to dealerships in the 1950s.
Cost of a New Starter Solenoid (1956-1958 Studebaker President)

| New Old Stock (NOS) OEM | $65.00+ (Varies by availability) |
| Shop Labor for Installation | $60 - $120 |
Frequently Asked Questions
Is the starter solenoid on the starter motor or on the fender?
For many 1956-1958 Studebaker models, the 12-volt starter solenoid is mounted remotely on the inner fender apron or firewall, not directly on the starter motor itself. This makes it easier to access and replace.
Can I replace just the solenoid myself?
Yes, this is a very feasible DIY project for a home mechanic. The solenoid is typically held by a couple of bolts and has a few electrical connections. The job requires only basic hand tools and should take less than an hour. Always disconnect the battery's negative terminal before beginning work.
What is the difference between a solenoid and a relay?
A solenoid is a type of relay. Both use a low-current signal to switch a high-current circuit. The term "solenoid" is used for the starter because it also performs a mechanical action—pushing the starter drive gear into place. However, on systems where the solenoid is mounted remotely, it functions purely as a high-current relay.
Could a bad ignition switch cause the same symptoms?
Yes, a faulty ignition switch could fail to send the initial signal to the solenoid, resulting in a no-crank, no-click situation. However, the classic "click but no crank" symptom points more directly to the solenoid or a high-amperage connection issue.
