Ignition Coil Guide for the 1956-1957 Lloyd L/600
Keep your classic Lloyd's engine running smoothly by understanding its simple ignition coil needs.
- The Lloyd L/600 requires a specific 6-volt, canister-style ignition coil.
- Failure symptoms include the engine not starting, stalling when hot, or running poorly.
- New aftermarket parts are the only viable option; brands like Standard Ignition offer reliable quality.
- Replacement is a simple DIY task that can be completed in under 30 minutes.
Understanding Ignition Coil Failure in Your Lloyd L/600
The ignition coil on a vintage vehicle like the Lloyd L/600 is a simple but essential component. Given the car's age, the original coil may fail due to internal components breaking down over time. Heat, vibration, and age are the primary enemies of these older canister-style coils. When it fails, it can leave you stranded, so recognizing the symptoms is key.
Symptoms of a Bad Ignition Coil
A failing ignition coil on your L/600 will cause noticeable engine problems. You will not get any diagnostic trouble codes like on a modern car; you must rely on observing how the engine behaves.
- Engine Won't Start: The most common and severe symptom. The engine will turn over with the starter, but it won't fire up because there is no spark being created.
- Stalling When Hot: The coil may work when the engine is cold but fail as it heats up. This can cause the engine to suddenly stall during a drive and refuse to restart until it has cooled down completely. This is a classic sign of an internally failing coil.
- Misfiring and Rough Running: If the coil is weak, it may not produce a strong enough spark. This can lead to the engine misfiring, hesitating during acceleration, running roughly, and a general lack of power.
Choosing the Right Aftermarket Ignition Coil
Finding a "new old stock" (NOS) or original equipment (OEM) ignition coil for a 1950s Lloyd is nearly impossible. Your only practical choice is a new aftermarket part. The good news is that modern aftermarket coils are often built to higher standards than parts from 70 years ago and can be more reliable.
The Lloyd L/600 uses a standard 6-volt electrical system with a single, canister-style ignition coil. This is a very common type of coil for the era, making it possible to find a suitable replacement.
Aftermarket Brand Quality
| Brand Tier | Brand(s) | Our Assessment |
|---|---|---|
| Good | Standard Ignition (SMP) | Standard Ignition is a well-regarded aftermarket manufacturer known for producing quality components that often meet or exceed original specifications. For a vintage application, their products are a reliable choice. |
| Standard | Spectra | Spectra offers a budget-friendly option. While some users report success, others have experienced shorter lifespans compared to more established brands. For a classic car that may not be a daily driver, it can be a cost-effective solution. |
Important: Verify Your System's Resistor Needs
Vintage ignition systems sometimes use an external ballast resistor. Before ordering, check if your L/600 has one. You must buy a coil that is compatible with your setup (either for use with an external resistor or one with an internal resistor). Using the wrong type can cause the new coil to overheat and fail quickly.
Cost of Replacing a Lloyd L/600 Ignition Coil
| Part Type | Cost Range |
|---|---|
| New Aftermarket Ignition Coil | $28.62 - $38.58 |
| New OEM | Not Available |
| Shop Labor | $60 - $90 |
Frequently Asked Questions
Can I replace the ignition coil myself?
Yes, this is a very easy job for a beginner. The coil is typically mounted on the firewall or inner fender and held by a simple bracket. It involves disconnecting the battery, removing a few wires and the main high-tension lead, and unbolting the bracket. The entire process usually takes less than 30 minutes.
Is the Lloyd L/600 a 6-volt or 12-volt system?
The 1956-1957 Lloyd L/600 uses a 6-volt electrical system. You must purchase a 6-volt ignition coil. A 12-volt coil will not produce a strong enough spark on a 6-volt system.
Where is the ignition coil located?
On the Lloyd L/600, the ignition coil is located in the engine bay, typically mounted to the firewall or an inner fender panel for easy access. It is a small canister with a wire coming from the top (the high-tension lead to the distributor) and two smaller wires for power.
Are there any recalls for the ignition coil on this vehicle?
No. There are no recalls or Technical Service Bulletins (TSBs) from the NHTSA for the ignition system on the Lloyd L/600. This is expected for a low-production vehicle of this age.
