# 88890142 Insulation Tester | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta insulation tester weighing 1.41 kg. It is a workshop instrument that applies its own test voltage, so it is treated as electrical test equipment rather than as an engine part.

## ⚙️ Key Features

-   1.41 kg
