Product Overview
A battery that repeatedly goes dead while mowing, charging voltage that climbs too high, or headlights that change sharply with engine speed can point to the regulator after the stator, battery, wiring, and grounds are tested. This regulator rectifies and limits stator output for compatible Briggs & Stratton systems.
The numbers and charging-system rating matter more than mower brand. Match the original regulator number, plug, mounting holes, stator configuration, and 9-amp system before ordering; a physically similar regulator for a different alternator output is not interchangeable.
Key Features & Performance
- 12V charging-system regulator/rectifier
- 9-amp application reference
- Controls alternator output to the battery
- Replacement for three listed Briggs & Stratton numbers
- Compact heat-sink housing with matching connector required
Replaces Part Numbers
- 698315
- 698102
- 150523
Common Uses
- Repairing a confirmed no-charge condition
- Correcting overcharging that damages a battery
- Replacing a heat-damaged or corroded regulator
- Restoring stable DC output on compatible outdoor power equipment
Technical Specifications
- Product Type: Voltage Regulator / Rectifier
- System Voltage: 12V
- Charging-System Rating: 9A application
- Compatible Brand: Briggs & Stratton

- Replacement Type: Aftermarket
Installation & Fitment
- Charge and test the battery before judging regulator output
- Inspect the stator leads, fuse, grounds, and connector for heat or corrosion
- Disconnect the battery before replacing the regulator
- Mount the regulator securely so its housing can dissipate heat and maintain ground where required
- Measure charging voltage at idle and governed speed and stop if output exceeds specification
Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.
Model, production date, serial number, engine or equipment configuration, installed options, and previous repairs can affect fitment. Compare the original part, identifying numbers, dimensions, connections, and mounting details before purchase.
Frequently Asked Questions
Q: Can this fix a battery that dies while mowing? A: It can if testing shows the regulator is not passing stator output. A weak battery, failed stator, wiring fault, or parasitic draw can cause the same result.
Q: Is this for every Briggs & Stratton engine? A: No. Match 698315, 698102, or 150523 and confirm the 9-amp charging system.
Q: Why does the regulator get hot? A: Regulators shed electrical heat during operation, but loose grounds, bad connectors, or incorrect stator output can cause damaging temperatures.
Q: How should output be checked? A: Use the engine manual's AC stator and DC charging tests with a known-good battery.
