3805228 Contactor Box Core | Genuine Volvo Penta Part

🔧 Product Description

Core deposit for a contactor box. It is the refundable charge raised against the old contactor box when the exchange unit is bought, and it comes back once the worn contactor box is returned. The line itself is an accounting entry rather than a part, so nothing ships against it on its own. Under Volvo Penta's core numbering the exchange unit it belongs to takes part number 3802228, which is the number to quote for the component itself. It is the only contactor box core in this run of numbers, 3805196 to 3805288, so there is nothing here to confuse it with. It belongs to the high-voltage side of a Volvo Penta electric or hybrid driveline, so removal of the old unit is work for a technician trained and authorised for high-voltage systems.

⚙️ Key Features

• Core deposit line, not a contactor box you can fit
• Belongs with the exchange unit, part number 3802228
• Refunded when the old contactor box is returned
• The only contactor box core in this run of numbers
• High-voltage driveline core - handling and return both need arranging

🔌 Function

As a line item it carries the refundable core charge on the exchange; the contactor box itself carries the high-voltage contactors that connect the traction battery to the rest of the driveline and isolate it again when the system is shut down.

⚠️ Common Signs of Failure

• This is a deposit line and has nothing to fail in itself; the signs below are what normally condemns the contactor box being exchanged
• Driveline that will not come live, or will not isolate when it is shut down
• No audible click on switching, or repeated clacking as the contactors chatter
• Isolation and interlock fault codes at the helm that return after the harness has been checked
• Power dropping out under load, or the system tripping itself off

🛠️ Service Notes

• The charge is refunded when the worn contactor box is returned, so keep the old unit and send it back rather than scrapping it
• Ordering this number on its own supplies no part - it goes on the order beside the exchange unit, part number 3802228
• This is a high-voltage driveline component - isolate and prove the system dead by the documented procedure before removing the old unit, and have the work done by a technician trained and authorised for high-voltage systems

📦 Condition

• Refundable core deposit - not a physical part
