# 3830375 Connecting Rail | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta connecting rail from the Starting System group, weighing 0.045 kg and listed for a single TWD series application. It is the heaviest of the three connecting rails listed here.

## 🚤 Compatibility

Typically suits:

-   Volvo Penta TWD1240VE

-   **Engine Family:** TWD

## ⚙️ Key Features

-   0.045 kg
-   Single TWD series application
-   Solid starting circuit link

## 🔌 Function

Carries current between two fixed contacts in the starting circuit as a rigid, self-supporting conductor.

## ⚠️ Common Signs of Failure

-   Sluggish cranking that briefly improves after the joint is disturbed
-   Rail or terminal hot to the touch after cranking
-   Corrosion building up on the contact faces
-   Arcing marks and burnt plating
-   Rail bent, cracked or distorted

## 🛠️ Service Notes

-   The other two connecting rails here are 3830374 at 0.036 kg and 3830439 at 0.025 kg, all three for a single TWD application — nothing but weight separates them in the published figures, so order by part number
-   Clean the mating faces to bright metal and torque the fixings properly; a loose joint generates the heat that destroys the rail
