3589487 Charging Regulator | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta charge distributor rated at 12 V with a maximum of 200 A, from the Alternator, Charging, Electric Motor, Electric Drives group, weighing 1.048 kg. It is the highest-rated of the three distributors listed together in the accessories catalogue, above the 70 A 873120 and the 160 A 3840597, and it is the only one restricted to 12 V. These distributors are specially adapted for Volvo Penta alternators and charge two independent battery circuits at once, with the starter motor battery always charged even when the second battery is flat.

🔌 Function

Splits the alternator's output between two battery circuits, charging each one without letting them discharge into each other.

⚠️ Common Signs of Failure

• One battery bank charging while another stays flat
• Charging voltage at the batteries well below the alternator output
• Distributor body running hot, or smelling of hot electronics
• Terminals discoloured, browned or bubbled from heat
• Batteries discharging into each other overnight

🛠️ Service Notes

• Confirm your system is 12 V and that total charging current stays within the 200 A maximum - 873120 and 3840597 cover the wider voltage range at 70 A and 160 A
• Check the cable sizes, crimps and terminal tightness first, since voltage drop in tired cabling gives exactly these symptoms
• Mount it where air can circulate, as a distributor working near its rating needs to shed heat
• The descriptive text for the charge distributors covers alternators of 12-24 V and 50-60 A, and states that distributor is equipped with a sensor for directly monitoring the voltage of the battery in use
• Check the rating printed against this part number against the charging system it will serve
