# 3805482 Charging Switch Unit Core | Genuine Volvo Penta Part

## 🔧 Product Description

Core deposit for a charging switch unit, in the Alternator, Charging, Electric Motor, Electric Drives group. It is the refundable charge raised against the old charging switch unit when the exchange unit is bought, and it comes back once the worn charging switch unit 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 3802482, which our own listings carry as a remanufactured charging switch unit. It is the only charging switch unit core in this listing block, so there is nothing here to confuse it with. It sits on the charging side of a Volvo Penta electric or hybrid driveline, so removing the old unit is work for a technician trained and authorised for high-voltage systems.

## ⚙️ Key Features

-   Core deposit line, not a charging switch unit you can fit
-   Belongs with the exchange unit, part number 3802482
-   Refunded when the old charging switch unit is returned
-   The only charging switch unit core in this block

## 🔌 Function

As a line item it carries the refundable core charge on the exchange; the unit itself makes and breaks the charging path, controlling when and how the supply is allowed through to the batteries.

## ⚠️ Common Signs of Failure

-   This is a deposit line and has nothing to fail in itself; the signs below are what normally condemns the charging switch unit being exchanged
-   Charging refusing to start, or dropping out part way through a charge
-   Charging and driveline warnings at the helm that return after the cables and connectors have been checked
-   Contacts heard chattering, or the unit running hot in service
-   Charge current well below what it should be, or reaching only part of the bank

## 🛠️ Service Notes

-   The charge is refunded when the worn charging switch unit 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 3802482
-   This is a high-voltage driveline component - isolate the system and prove it dead by the documented procedure before the old unit is disturbed, and have the work done by a technician trained and authorised for high-voltage systems

-   Refundable core deposit - not a physical part
