Plymouth Colt Accessory Safety Relays

Plymouth Colt Accessory safety relays

Starting at $75.95, AutoBuffy stocks 1 accessory safety relays from Standard Ignition for the Plymouth Colt. This relay acts as a protective switch that controls power to non-essential electrical accessories, cutting the circuit if current spikes dangerously. When it fails, accessories go dead or draw unprotected power, risking blown fuses, damaged modules, or an electrical fire.

Signs your Plymouth Colt needs a new accessory safety relay

  • Multiple accessories — interior lights, radio, power windows — stop working simultaneously with no blown fuse found
  • Accessories only work intermittently, cutting out when the vehicle hits a bump or the cabin temperature rises
  • Relay clicks rapidly or chatters when you turn the ignition to the accessory position
  • Visible burn marks, melted plastic, or a burning smell near the underhood or cabin fuse/relay box
  • Battery drains overnight even though all accessories appear to be off, suggesting the relay is stuck closed
  • Accessories remain powered after the ignition is switched fully off, indicating the relay is not opening the circuit

Which accessory safety relay should you buy for your Plymouth Colt?

The main decision is whether to match the OEM relay specification exactly or upgrade to a heavy-duty unit with a higher amperage rating. You also need to confirm the relay form factor — blade-terminal micro relays and standard ISO relays are not interchangeable even when the amperage rating looks the same.

OEM-equivalent replacement
Best for
Restoring factory function with guaranteed fit
What you get
Exact amperage, pin count, and footprint matched to the original; plug-and-play installation with no wiring changes
Heavy-duty / high-amperage relay
Best for
Vehicles with aftermarket audio, lighting, or winch accessories that push near the stock relay's limit
What you get
Higher continuous current rating reduces heat buildup and extends service life under elevated electrical loads
Sealed / weatherproof relay
Best for
Vehicles in high-humidity climates or where the relay is mounted in an exposed underhood location
What you get
Sealed housing prevents moisture and corrosion from reaching contacts, reducing intermittent-failure risk
Multi-pack / value set
Best for
DIY owners who want a spare on hand or fleet vehicles with multiple units of the same Colt
What you get
Cost savings per unit; identical relays can also serve as a quick swap-and-test diagnostic tool

Replacing the accessory safety relay on a Plymouth Colt

Easy⏱ 15–30 minutesRelay puller or needle-nose pliersMultimeter (for pre- and post-installation verification)Flashlight or work lightVehicle owner's manual or fuse box diagram

Locate the accessory safety relay using the fuse box diagram on the underside of the fuse box cover or in the owner's manual, then use a relay puller or needle-nose pliers to pull the relay straight out of its socket without rocking it side to side. Press the new relay firmly into the socket until all pins seat fully, then restore power and test all affected accessories before closing the fuse box cover.

Frequently asked questions

How much does it cost to replace accessory safety relays on a Plymouth Colt?
Parts start at $75.95 for an accessory safety relay that fits the Plymouth Colt. The relay itself is inexpensive; total cost depends on whether you replace it yourself or pay a shop. DIY takes under 30 minutes in most cases, so professional labor charges are typically one hour or less at shop rates.
Can a bad accessory safety relay drain the battery on a Plymouth Colt?
Yes. An accessory safety relay that is stuck in the closed position keeps the accessory circuit energized even after the ignition is off. This creates a constant parasitic draw that will fully discharge the battery overnight or within a day or two, and the drain stops immediately once the faulty relay is replaced.
Is it safe to drive a Plymouth Colt with a failed accessory safety relay?
Short-term driving is generally possible, but it carries real risk. A relay stuck open disables powered accessories, which may include safety-relevant items like brake lights or horn on some platforms. A relay stuck closed can cause overheating of wiring. Replace it promptly rather than treating it as a minor issue.
How do I test whether the accessory safety relay is the problem on my Plymouth Colt?
Swap the suspect relay with an identical relay from another position in the fuse box — many vehicles use the same relay in multiple slots. If the dead accessories come back to life after the swap, the original relay is faulty. You can also test coil resistance and contact continuity with a multimeter to confirm failure.
How long does an accessory safety relay last on a Plymouth Colt?
Most relays are rated for tens of thousands of switching cycles and can last the life of the vehicle under normal conditions. Heat, moisture, voltage spikes from failing alternators, and consistently overloaded circuits all shorten relay life significantly. Vehicles with heavy aftermarket electrical accessories tend to see earlier relay failure than stock configurations.
Will any relay with the same amperage rating fit my Plymouth Colt?
Not necessarily. Amperage rating must match, but so must the relay's pin layout, terminal type, and coil voltage. A relay with identical specs but a different footprint will not seat correctly in the fuse box. Always cross-reference your Plymouth Colt's year, make, and model against the part listing before purchasing to confirm direct fitment.
