Because relay usage varies by harness layout, ECU version, and production break, the safest fitment path is to match this relay to the exact Volvo Penta electrical schematic and serial-number-based application before ordering.\u003c\/p\u003e\n\u003ch2\u003eSerial Number Fitment Notice\u003c\/h2\u003e\n\u003cp\u003eMatch Volvo Penta part number \u003cstrong\u003e3171420\u003c\/strong\u003e to your engine serial number and the correct Volvo Penta electrical-system diagram before ordering. Relays can look similar across different fuse holders, terminal boxes, and engine harness assemblies, so exact schematic match matters more than appearance alone.\u003c\/p\u003e\n\u003ch2\u003eWhen This Part Needs Replacement\u003c\/h2\u003e\n\u003cp\u003eThis relay should be replaced when it fails to switch properly, causes intermittent electrical operation, shows heat damage or corrosion at the terminals, or is identified as faulty during electrical-system diagnosis. It is also worth checking anytime related fuse-holder, relay-box, or harness components are already apart. This service guidance is a practical inference based on the part's repeated use in Volvo Penta electrical-system assemblies.\u003c\/p\u003e\n\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\n\u003cp\u003eConfirm the exact application in the correct Volvo Penta schematic before installation, and compare the removed relay carefully against the replacement part. Inspect the relay socket, terminals, fuse-holder area, and surrounding harness condition before reassembly. On Volvo Penta electrical systems, exact relay match matters more than a quick visual comparison.\u003c\/p\u003e\n\u003ch2\u003eAlternate\/Superseded Part Numbers\u003c\/h2\u003e\n\u003cp\u003eCurrent parts references show \u003cstrong\u003e3171420\u003c\/strong\u003e as the active Volvo Penta OEM number. Reviewed sources also show it as the replacement for earlier Volvo Penta numbers \u003cstrong\u003e4786690\u003c\/strong\u003e and \u003cstrong\u003e21072016\u003c\/strong\u003e, while one current dealer listing notes \u003cstrong\u003e20374662\u003c\/strong\u003e and \u003cstrong\u003e21072016\u003c\/strong\u003e as superseded references into 3171420. A newer Marine Parts Express listing also shows \u003cstrong\u003e24966470\u003c\/strong\u003e as the updated replacement for 3171420 in that catalog, so serial-number-based schematic confirmation is especially important.\u003c\/p\u003e\n\u003ch2\u003eParts Desk Insight\u003c\/h2\u003e\n\u003cp\u003eWith relays like this, the easy mistake is matching only by pin style or housing size. Checking the exact Volvo Penta electrical diagram first usually saves a lot of hassle, especially when the same relay family appears across marine, industrial, and generator applications.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShipping:\u003c\/strong\u003e Ships same or next day for fast Canada wide shipping. ⚓\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43563998347300,"sku":"3171420","price":36.4,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/ce8b365d-8f00-4cf3-99a0-8ecffd006791.png?v=1776481666","url":"https:\/\/marisolmarine.com\/products\/volvo-456","provider":"Marisol Marine Company","version":"1.0","type":"link"}
