Starter Solenoid Guide for the 1955-1956 Studebaker E12 Truck
Having trouble starting your classic Studebaker truck? It could be the starter solenoid.
- A single loud click with no crank is the most common symptom of a bad starter solenoid.
- For a 1955-1956 Studebaker E12, a new aftermarket solenoid from a brand like Standard Ignition is the most practical and reliable option.
- Before replacing the solenoid, always check that your battery is charged and that all electrical connections are clean and tight, as this is a frequent issue on older vehicles.
- Verify if your truck has a 6-volt (common in 1955) or 12-volt (common in 1956) system before ordering parts.
Is Your Studebaker E12's Starter Solenoid Failing?
For a classic truck like the 1955-1956 Studebaker E12, starting issues are common, but often simple to fix. One of the most frequent culprits is a failing starter solenoid. Recognizing the symptoms early can save you from being stranded. Because these trucks have simpler electrical systems, diagnosing the problem is usually straightforward.
Common Symptoms of a Bad Starter Solenoid
- Single, loud click when turning the key: This often means the solenoid is receiving power from the ignition switch but isn't successfully sending power to the starter motor.
- No sound at all: If you turn the key and nothing happens, the solenoid might not be getting power or may have failed completely.
- Engine cranks slowly: A solenoid that isn't making a solid connection can restrict the amount of power reaching the starter, causing a weak or slow crank.
- Intermittent starting: The truck starts fine one day but won't crank the next. This can point to worn internal contacts in the solenoid.
Choosing a New Aftermarket Solenoid
Finding a "New Old Stock" (NOS) or original OEM starter solenoid for a 1955-1956 Studebaker is nearly impossible and would be very expensive. For most owners, a new aftermarket part is the most practical and reliable choice. Aftermarket parts are designed to meet or exceed the original specifications and are readily available.
Standard Ignition is a well-known brand that produces replacement solenoids compatible with these classic trucks. They have a long history in the industry and manufacture parts designed to be durable replacements for original equipment. For a vehicle of this age, a quality aftermarket part from a reputable brand is a solid investment in reliability.
Pro Tip: Many starting problems on 6-volt systems are caused by poor connections or undersized battery cables. Before replacing the solenoid, ensure your battery is fully charged, and all cable connections at the battery, frame, and starter are clean and tight.
Estimated Costs for Replacement
Replacing a starter solenoid is one of the more affordable repairs for your starting system. The primary cost is the part itself, as labor is minimal for this job.
| Item | Estimated Cost |
|---|---|
| New Aftermarket Starter Solenoid | $49.14 - $70.77 |
| Shop Labor | $100 - $200 |
| Total Estimated Cost | $149.14 - $270.77 |
Frequently Asked Questions (FAQ)
Is the starter solenoid on the starter or mounted separately?
On many Studebaker trucks of this era, the solenoid is mounted on the starter itself. However, some models and years used a dash or fender-mounted solenoid. It's important to check your specific truck's configuration before ordering a part.
Can I replace the starter solenoid myself?
Yes, this is a very DIY-friendly job for someone with basic mechanical skills and tools. The solenoid is typically easy to access and is held on by a few bolts and electrical connections. Always disconnect the battery before beginning any work on the starting system.
What's the difference between a 6-volt and 12-volt solenoid?
They are not interchangeable. A 6-volt system requires a 6-volt solenoid, and a 12-volt system needs a 12-volt solenoid. Using the wrong one can cause it to fail quickly or not work at all. The 1955 models were typically 6-volt, while 1956 models transitioned to 12-volt systems. Verify your truck's voltage before purchasing.
My new solenoid just clicks, but the old one would sometimes work. Is the new part bad?
Not necessarily. A new solenoid requires a proper voltage signal to activate. If your wiring, ignition switch, or battery connections are weak, it might not be enough to trigger the new part. The problem could be a high-resistance starter motor drawing too much current, or an issue elsewhere in the starting circuit.
