Description
This Sea-Doo voltage regulator-rectifier, part numbers 278001969 / 278001581, is used in the electrical charging circuit: it rectifies the current produced by the alternator and regulates the voltage supplied to the onboard electrical system and the battery. It can replace a defective regulator after the charging circuit has been diagnosed. The 4-TEC applications listed below include the Rotax 1503 engine for the 2002 to 2007 period. The listing also mentions RFI/DI applications, which are distinguished separately and should be verified by part number and connector.

Why Replace the Regulator-Rectifier?
Faulty charge regulation can cause insufficient charging or excessive voltage, affecting the battery and electrical equipment. These symptoms can also be caused by the battery, stator, or connections: the entire circuit must be checked before replacement.
- Battery discharges despite engine use
- Abnormal charging voltage detected during diagnosis
- Electrical warning or intermittent onboard electrical system malfunction
- Damaged, overheated, or oxidized connectors requiring inspection
Check the condition of connections, grounds, and the battery during maintenance and before seasonal commissioning. Replace the regulator when the diagnosis confirms it is necessary, then check the charging voltage according to the values and procedure specified by the manufacturer.
