1625880 Charge Regulator | Genuine Volvo Penta Part

🔧 Product Description

This is a genuine Volvo Penta charge regulator from the alternator, charging, electric motor and electric drives group. It controls the alternator's field output to hold battery charging voltage within the correct range, protecting the batteries and connected electrical equipment. It fits a broad span of Volvo Penta TD, TID, TWD and TAD series diesel engines and supersedes the earlier charging regulator 1606935.

🚤 Compatibility

• Engine Family: TD, TWD, TID, D, TAD

🔌 Function

The charge regulator senses system voltage and adjusts the alternator field current so charging output stays at the specified level regardless of engine speed or electrical load. This prevents both undercharging and overcharging of the vessel's batteries.

⚠️ Common Signs of Failure

• Batteries persistently undercharged or going flat despite running hours
• Overcharging symptoms such as boiling electrolyte, excessive water loss or swollen batteries
• Charging voltage that fluctuates or surges instead of holding steady
• Charge warning lamp illuminated or flickering while the engine is running
• Bulbs and electronic accessories failing prematurely from unstable system voltage

🛠️ Service Notes

• Isolate the batteries before disconnecting anything in the charging circuit, and take care not to short the output terminal against structure
• Before condemning a regulator, clean and check the battery terminals, main earth or return connections and the sensing wiring — poor connections and corroded earths cause most of the charging complaints blamed on regulators
• Check the battery itself is serviceable and the drive belt is in good condition and tensioned by the method given for your engine; a slipping belt looks exactly like a charging fault
• Mount the regulator so its mounting face is clean and it sits flat with the airflow it was designed for — these units rely on getting rid of their own heat
• After fitting, measure the charging voltage with a meter across the battery with the engine running and compare it against the figures in the workshop manual for your engine, rather than judging by a panel lamp
