24550877 Insulation Monitor | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta insulation monitor, published at 0.181 kg. No group and no engine applications are recorded against this number, so the part number is the only thing that identifies it — order by number and confirm it against the electrical system it is going into rather than by appearance. Nothing else in the listing distinguishes it, and no supersession is recorded either way, so it neither replaces nor is replaced by another number here.

⚙️ Key Features

• 0.181 kg
• Monitors insulation resistance on an unearthed electrical system
• No engine applications listed against this number
• No supersession recorded — this number does not consolidate any older number

🔌 Function

Continuously measures the insulation resistance between an unearthed electrical system and the hull or chassis it sits in, and raises an alarm when that resistance falls far enough to indicate a fault, so an earth leak is found and cleared before a second fault can make the system dangerous.

⚠️ Common Signs of Failure

• A persistent insulation or earth fault warning that will not clear after the wiring has been checked
• The system refusing to go live, or dropping out shortly after start-up
• Intermittent alarms that come and go with damp weather or with one particular circuit running
• No response at all when the unit's own test function is operated
• Dead or blank indicators with the supply confirmed present at the unit

🛠️ Service Notes

• An insulation monitor normally alarms because something else has failed — trace and clear the earth fault before condemning the monitor itself
• No applications are listed against this number, so check it against the documentation for your installation before ordering

📦 Condition
