Why Replace the Voltage Regulator-Rectifier?

A faulty regulator-rectifier can lead to chronic overcharging or undercharging of the battery, causing progressive electrical failures and irreversible damage to onboard equipment. Common symptoms of a faulty regulator include:

• Battery no longer charging or discharging quickly
• Unstable or flickering lights or electrical equipment
• Repeated starting difficulties despite a new battery
• Abnormal overheating of the electronic housing

Checking the regulator-rectifier is recommended at the start of each season or as soon as electrical problems appear, in order to prevent a complete breakdown during navigation and protect your Sea-Doo's entire electrical system.
