Choosing the Right Ignition Coil for Your 1984-1988 Dodge Mini Ram
Solve starting problems and rough idling by understanding how to pick the best new aftermarket ignition coil for your classic van.
- A failing ignition coil causes common issues like stalling, misfiring, and no-starts.
- Replacement is very easy, requiring only basic tools and less than 30 minutes.
- For a stock engine, a standard replacement from NGK or Standard Ignition is a reliable choice; performance coils are not necessary.
- Testing the old coil with a multimeter can confirm it's the source of the problem before you buy a new part.
Is Your Mini Ram Stalling or Hard to Start? It Could Be the Coil.
The single, canister-style ignition coil on these classic Dodge vans is a common part to fail after decades of heat and use. When it starts to go bad, the symptoms are usually obvious and can leave you stranded if ignored. The good news is that it's an affordable and easy part to replace yourself.
Choosing the Right Aftermarket Ignition Coil
Since new original Mopar coils for this van are generally not available, the aftermarket is your only option. Luckily, many reputable brands make quality replacements. For a stock engine, you don't need a high-voltage racing coil; a standard replacement will work perfectly. Aftermarket coils for this van can be broken down into three general tiers:
| Tier | Brands | Best For |
|---|---|---|
| Performance Upgrade | MSD, Accel | Owners with other engine modifications who want the hottest, most reliable spark. MSD is often preferred over Accel in forum discussions for modern reliability. |
| Standard Replacement (OEM Quality) | NGK, Standard Ignition | Daily drivers and owners who want a reliable, long-lasting part that meets or exceeds original factory quality. These are trusted brands among mechanics. |
| Economy | Spectra, WAI Global, Global Parts | Budget-conscious repairs where getting the van back on the road is the main priority. Quality can be inconsistent with house brands. |
Pro Tip: Test Before You Replace. You can test your old coil with a multimeter to see if it's bad. Set the multimeter to ohms (Ω) and check the resistance between the primary terminals (+ and -) and the secondary winding (positive terminal to the center tower). A healthy coil should have a primary resistance between 0.4 and 2 ohms and a secondary resistance between 6,000 and 15,000 ohms. If the readings are far outside this range, the coil is bad.
Frequently Asked Questions
Can I replace the ignition coil myself?
Yes, absolutely. This is one of the easiest jobs you can do on your Mini Ram. It involves disconnecting the battery, unplugging two small wires and the main coil wire, and removing two 10mm bolts that hold the coil bracket. The entire job takes less than 30 minutes with basic hand tools.
Do I need a high-performance coil like MSD or Accel?
For a stock engine, a high-performance coil is not necessary. A standard replacement from a brand like NGK or Standard Ignition will provide plenty of spark. An upgraded coil is only beneficial if you have other performance modifications like an upgraded ignition module, carburetor, or internal engine work.
What are the signs of a bad ignition coil?
The most common signs are engine misfires (sputtering or shaking), difficulty starting, sudden stalling, poor acceleration, and a noticeable drop in fuel economy. In some cases, a completely failed coil will result in the engine cranking but not starting at all because there is no spark.
My new coil failed quickly. What could be the cause?
Heat is the main enemy of ignition coils. If a replacement coil fails prematurely, check for underlying issues. A bad ground connection can cause the coil to overheat. Also, look for exhaust leaks that might be blowing hot gas directly onto the coil. On these older vans, other failing ignition components can also put extra strain on the coil, causing it to burn out.
