Standard Ignition MC2301 Starter Relay

Starter Relay for 12V Starting Systems

Standard Ignition MC2301 is a 12-volt starter relay built for electrical starting circuits that need reliable switching under the hood. It uses a male, 4-terminal, threaded design and is built with composite housing, aluminum contacts, and epoxy sealing to help maintain performance in heat, dust, and moisture.

Key Features

• 12-volt starter relay for starting system service
• Male terminal design with 4 threaded terminals
• Composite housing helps protect against harsh under-hood temperatures
• Aluminum contacts support durability and long service life
• Epoxy-sealed construction helps resist dust, heat, and moisture
• Manufactured in a TS16949 and ISO9001 certified facility

Detailed Description

Standard Ignition MC2301 is a starter relay intended for electrical charging and starting applications where dependable current control is required. The relay’s threaded terminal layout supports secure connections, while the composite housing and epoxy protection help it stand up to demanding engine-bay conditions. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. If you are servicing a starter relay on a vehicle such as a Honda Civic or Toyota Corolla, MC2301 provides a direct replacement option for 12V starting circuits.

Common Problems It Can Help Address

• No-crank condition when the ignition key is turned
• Intermittent starter engagement
• Clicking at the relay with weak or inconsistent starter operation
• Electrical connection issues caused by heat or moisture exposure
• Starting circuit faults related to worn relay contacts

Installation Notes and Tips

Verify terminal style, terminal count, and voltage before installation. Match the threaded male terminals to the original relay connection layout and confirm the vehicle uses a 12-volt starting circuit. For fitment-based searches, this part is commonly referenced for starter relay replacement on Honda Civic and Toyota Corolla applications where the original relay matches the same electrical configuration. Standard Ignition MC2301 should be installed with the ignition system powered down and all connections checked for tightness and corrosion.
