Your 1955-1956 Studebaker E13 Starter Solenoid: A Practical Guide
Get your classic Studebaker starting reliably with the right information on starter solenoids.
- A single loud 'click' with no engine crank is the most common sign of a failed solenoid on these trucks.
- Before replacing the solenoid, always check for clean, tight connections and heavy-gauge battery cables, as this is a frequent issue on 6-volt systems.
- New aftermarket solenoids from a brand like Standard Ignition are the most practical and reliable replacement option.
- Replacement is a simple DIY job that typically takes less than an hour with basic tools.
Is Your Studebaker's Starter Solenoid Failing?
A bad starter solenoid can leave you stranded. Because these trucks are from the 1950s, the symptoms are usually straightforward. Pay attention to how your truck behaves when you try to start it.
Common Symptoms of a Bad Solenoid:
- Single Loud "Click": You turn the key and hear one loud click, but the engine doesn't crank. This often means the solenoid is engaging but failing to pass high current to the starter.
- No Sound at All: If you turn the key and get silence, the solenoid might have failed completely and isn't even trying to activate.
- Rapid Clicking: A series of fast clicks can sometimes point to a solenoid problem, but it more often indicates a low battery that can't supply enough power to keep the solenoid engaged.
- Engine Cranks Slowly: If the internal contacts of the solenoid are corroded or worn, they can create high resistance. This chokes the power going to the starter, causing a slow, weak crank even with a good battery.
- Starter Stays On: In rare cases, the solenoid can get stuck in the "on" position, causing the starter to keep running even after the engine has started. This can cause serious damage to the starter and flywheel.
Check Your Cables First!
For these 6-volt systems, problems are often in the wiring. Before replacing the solenoid, check your battery cables. They should be thick (at least 0-gauge or 00-gauge), and the connections at the battery, frame, and starter must be perfectly clean and tight. A forum post from a 1955 Studebaker owner highlighted that slow cranking after a solenoid replacement was due to cable and connection issues.
Choosing the Right Aftermarket Solenoid
For a 1955-1956 vehicle, finding a “New Old Stock” (NOS) OEM solenoid is nearly impossible and not always ideal, as rubber and other materials can degrade over 70 years in a box. The most practical and reliable choice is a new aftermarket part from a reputable brand.
Standard Ignition (Standard Motor Products):
Standard Ignition is a well-known and widely available brand that produces parts for classic vehicles. Their starter solenoids are often built with heavy-duty copper contacts and more windings than original parts, which helps create a stronger magnetic field and handle the electrical load better. This is important for the high demands of a 6-volt starting system. While some general online discussions mention occasional quality issues with certain product lines from any large manufacturer, Standard is generally considered a reliable choice for classic truck owners.
| Part Type | Part Cost | Shop Labor Cost | Total Estimated Cost |
|---|---|---|---|
| New Aftermarket (Standard Ignition) | $49.14 - $70.77 | $90 - $180 | $139.14 - $250.77 |
| New Old Stock (OEM) | Varies (Rare) | $90 - $180 | Varies widely |
DIY Feasibility
Replacing the starter solenoid on an E13 is a straightforward job for a DIY mechanic. The solenoid is usually mounted on the starter motor or on the firewall, making it easy to access. The job requires basic hand tools and should take less than an hour. Always disconnect the battery before beginning any work on the starting system.
Frequently Asked Questions (FAQ)
Why does my engine still crank slowly with a new solenoid?
This is a common issue on 6-volt systems. The problem is likely not the new solenoid but high resistance elsewhere. Check that you have very thick battery cables (0-gauge or larger), that all connections are scraped clean to bare metal, and that the starter itself doesn't have worn bushings.
Is there a recall on the starter solenoid for my Studebaker E13?
No, there are no recalls issued by the NHTSA for the starter solenoid on 1955-1956 Studebaker trucks. Recalls for vehicles of this age are extremely rare.
I just hear a single click. Is it the starter or the solenoid?
A single, loud click strongly points to the solenoid. The click is the sound of the solenoid activating, but it's failing to send power to the starter motor. If you heard rapid clicking, the battery would be the first thing to check.
Can I repair my old solenoid?
While it was once common to repair solenoids, it is no longer practical. Modern aftermarket replacements are inexpensive, readily available, and often made with better materials than the 70-year-old original. Replacement is the recommended and more reliable option.
Technical Specifications
Varies by system (6-volt or 12-volt). Ensure the replacement matches your vehicle's original electrical system voltage.
