Introduction
This manual provides essential information for the installation, operation, and maintenance of your Secura Magnetic Solenoid Switch. This component is designed to be compatible with specific MTD lawn tractor models. Please read these instructions carefully before proceeding with installation or use to ensure proper function and safety.
Safety Information
Always observe the following safety precautions when working with electrical components and machinery:
- Disconnect Power: Before attempting any installation, maintenance, or repair, ensure the lawn tractor's battery is disconnected to prevent accidental starting or electrical shock.
- Wear Protective Gear: Use appropriate personal protective equipment, including safety glasses and gloves.
- Verify Compatibility: Confirm that this solenoid switch is the correct replacement part for your specific lawn tractor model and year. Pay close attention to the number of flat pins. This model features a single flat pin.
- Professional Installation: If you are unsure about any step, consult a qualified technician or refer to your lawn tractor's service manual.
- Avoid Short Circuits: Ensure all connections are secure and properly insulated to prevent short circuits.
Product Description and Features
The Secura Magnetic Solenoid Switch acts as an electrical relay, connecting the battery to the starter motor when the ignition key is turned. This allows the engine to crank and start. This specific model is characterized by its single flat-pin connector.
- Type: Magnetic Solenoid Switch
- Connector: Single flat pin
- Function: Engages starter motor

Compatibility
This magnetic solenoid switch is compatible with the following lawn tractor model:
- MTD RH 115 13A1450C600 Lawn Tractor
It is typically found in models manufactured during the years:
- 2000
- 2001
- 2002
Important: Always verify the existing solenoid's pin configuration (single flat pin vs. two flat pins) before purchasing and installing to ensure correct fitment.
Setup and Installation
Follow these general steps for replacing the magnetic solenoid switch. Specific steps may vary slightly depending on your lawn tractor model. Always refer to your tractor's owner's manual for detailed instructions.
- Prepare for Installation: Park the lawn tractor on a flat, level surface. Engage the parking brake. Turn off the engine and remove the ignition key.
- Disconnect Battery: Disconnect the negative (-) battery cable first, followed by the positive (+) battery cable. This prevents accidental electrical shorts.
- Locate Old Solenoid: Identify the existing magnetic solenoid switch, typically mounted near the battery or starter motor.
- Note Wiring: Carefully observe and make a diagram or take photos of how the wires are connected to the old solenoid. There will typically be two large terminals (for battery and starter) and one or more small control terminals. This Secura solenoid has one small flat-pin control terminal.
- Remove Old Solenoid: Disconnect all wires from the old solenoid. Then, unbolt or unmount the old solenoid from its position.
- Install New Solenoid: Mount the new Secura solenoid switch in the same location as the old one. Ensure it is securely fastened.
- Connect Wiring: Reconnect the wires to the new solenoid according to your diagram or photos. Ensure the large battery cable connects to the correct large terminal, the large starter cable connects to the other large terminal, and the small control wire connects to the flat-pin terminal. Tighten all connections securely.
- Reconnect Battery: Reconnect the positive (+) battery cable first, then the negative (-) battery cable.
- Test Functionality: Attempt to start the lawn tractor. If the engine cranks and starts, the installation was successful. If not, refer to the Troubleshooting section.

Operation
The magnetic solenoid switch operates automatically as part of the lawn tractor's starting system. When the ignition key is turned to the 'START' position, a small electrical current flows through the flat-pin control terminal, activating the solenoid. This activation creates a magnetic field that pulls a plunger, closing the circuit between the battery and the starter motor. This allows a large current to flow to the starter, engaging the engine. Once the key is released from 'START', the solenoid deactivates, opening the circuit and disengaging the starter.
Maintenance
The Secura magnetic solenoid switch is designed for durability and typically requires minimal maintenance. However, periodic checks can help ensure its longevity and reliable operation:
- Inspect Connections: Annually, or if starting issues arise, inspect all wire connections to the solenoid. Ensure they are clean, tight, and free from corrosion. Loose or corroded connections can impede current flow.
- Clean Solenoid: Keep the exterior of the solenoid clean from dirt, debris, and moisture. Use a dry cloth to wipe it down. Avoid using harsh chemicals.
- Check for Damage: Visually inspect the solenoid for any signs of physical damage, such as cracks in the housing or bent terminals.
Troubleshooting
If your lawn tractor is experiencing starting problems after installing or while using the Secura magnetic solenoid switch, consider the following:
| Symptom | Possible Cause | Solution |
|---|---|---|
| Engine does not crank, no clicking sound from solenoid. | Dead battery, faulty ignition switch, open safety switch, loose/corroded connections to solenoid. | Check battery charge. Inspect ignition switch and all safety switches (e.g., seat, PTO, brake). Clean and tighten all solenoid connections. |
| Solenoid clicks but engine does not crank. | Low battery charge, corroded battery terminals, faulty starter motor, internal solenoid failure (rare). | Charge or replace battery. Clean battery terminals. Test starter motor. If battery and starter are good, the solenoid may be faulty and require replacement. |
| Solenoid gets hot. | Excessive current draw, prolonged engagement, internal short. | Check for short circuits in the starter circuit. Ensure the solenoid is not being held in the 'ON' position for too long. Replace if internal fault is suspected. |
