The part number **17841** is most commonly associated with a specific series of **Automotive Starter Motors** and specialized **Voltage Regulators** used in heavy-duty or agricultural equipment. Below is a breakdown of the technical specifications and variants for parts labeled 17841. --- ## 1. Primary Component: The 17841 Starter Motor In the automotive and industrial aftermarket (using the Lester catalog system), **17841** refers to a 12-volt starter motor typically found in John Deere equipment and various marine applications. ### Technical Specifications | Feature | Specification | | :--- | :--- | | **Voltage** | 12 Volts | | **Power Rating** | 1.2 kW - 1.4 kW | | **Rotation** | Clockwise (CW) | | **Tooth Count** | 9 or 10 Teeth (depending on variant) | | **Type** | Permanent Magnet Gridded Reduction (PMGR) | ### Common Applications * **John Deere:** Utility Tractors, Skid Steer Loaders, and Gator Utility Vehicles. * **Kawasaki:** Used in several industrial engines (specifically the FD series). * **Marine:** Various small inboard/outboard engine configurations. --- ## 2. Alternate Component: Voltage Regulator 17841 In some electronic distribution catalogs, "17841" refers to a specific **Voltage Regulator** or **Rectifier** unit used to stabilize output from an alternator. ### Key Functions * **AC to DC Conversion:** Converts the alternating current from the stator to direct current for battery charging. * **Thermal Protection:** Includes heat-sink fins to dissipate heat during high-load charging cycles. * **Voltage Limitation:** Ensures the battery does not exceed ~14.4V to prevent cell damage. --- ## 3. Maintenance and Troubleshooting If you are working with a 17841 electronic part, use the following checklist for diagnosis: 1. **Terminal Check:** Ensure the "B+" terminal (Battery positive) is free of corrosion. 2. **Solenoid Test:** If it is a starter, check if the solenoid clicks. If it clicks but doesn't spin, the internal brushes or the motor winding may be burnt. 3. **Voltage Drop Test:** Measure the voltage at the part while under load; a drop below 9.6V usually indicates a failing battery rather than a faulty 17841 unit. ---
