21106105 Housing | Genuine Volvo Penta Part

🔧 Product Description

A genuine Volvo Penta electrical connector housing used in engine cable-and-fuse installations. On D6-300A-G and TAD580-TAD583VE systems it forms part of the sealed connector hardware associated with the engine harness, sensors, relay/fuse equipment or installation interface. It is not a structural engine housing; its purpose is to locate and protect electrical terminals.

• Engine Family: TAD, D
• HP Range: 300-480 HP

🔌 Function

Holds and aligns electrical terminals, maintains connector polarity and protects the connection from moisture, vibration and accidental short circuits.

⚠️ Common Signs of Failure

• Loose terminals backing out of the connector
• Moisture or corrosion inside the housing
• Broken locking tab allowing the connector to separate
• Intermittent sensor, relay or power-circuit faults
• Heat damage caused by a high-resistance terminal connection

🛠️ Service Notes

• Isolate the batteries first, and note which way the housing sits and how the harness runs into it before anything is disturbed
• Move terminals across one at a time into the same cavity positions, releasing each locking tab with a proper extraction tool rather than pulling on the wire
• Check every terminal clicks fully home and locks before the housing is closed; a terminal that is not seated will back out under vibration
• Make sure all seals, grommets and blanking plugs are present and undamaged, and leave unused cavities plugged so the housing keeps water out
• Support and route the harness so nothing hangs on the housing, and check the connection is dry after the first run
