Why Replace the Voltage Regulator-Rectifier?

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

Battery no longer charges or discharges 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, to prevent a complete failure while riding and preserve the entire electrical system of your Sea-Doo.
