Product Overview
An overcharging battery, low charging voltage, repeated battery failure, blown fuses, or unstable electronics can point to the regulator after stator output, grounds, battery condition, and connectors are tested. This unit converts and controls charging-system output for the matching Sea-Doo electrical layout.
Burned terminals and water intrusion must be repaired or the new regulator can fail again. Match plug shape, wire count, mounting, and reference number.
Key Features & Performance
- 12-volt charging-system rectifier/regulator
- Controls stator output to the battery and electrical system
- Cross-references 278001241 and 278001554
- For matching DI/RFI wiring configurations
Replaces Part Numbers
- 278001241
- 278001554
Common Uses
- Repairing low or excessive charging voltage
- Replacing a heat-damaged regulator
- Correcting repeated battery discharge after stator testing
Technical Specifications
- Product Type: Rectifier/voltage regulator
- System Voltage: 12V
- Condition: New
- Replacement Type: Aftermarket
Installation & Fitment
- Load-test the battery and measure stator output first
- Clean and tighten battery and engine grounds
- Replace burned connectors rather than only the regulator
- Mount for proper heat transfer and verify charging voltage at multiple RPM
Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.
Model, engine-management type, connector, wire count, and production date affect compatibility. Match both reference and physical plug.
Frequently Asked Questions
Q: Can a bad regulator overcharge the battery? A: Yes. Failed regulation can create excessive or insufficient voltage.
Q: Will this fix a failed stator? A: No. Stator output must be tested separately.
Q: Why do connectors burn? A: Loose or corroded terminals create resistance and heat.
Q: Does it fit every Sea-Doo 951? A: No. Use the specific DI/RFI model list and connector comparison.
