㉦Mercedes Ke-Jetronic㉦ - OVP Relay Test (Overvoltage Protection Explained)

In this episode of the KE-Jetronic Logic Series, we test the OVP relay (Overvoltage Protection relay) and explain its role in the system. The OVP relay protects the electronic control units from excessive voltage and supplies power to several important components. In this video we cover: • What the OVP relay does • Which components it powers (ECU, ABS, idle valve) • Why the fuse on top is critical • How to test the fuse visually and electrically • How to verify ECU power without removing the relay • Why replacing the OVP blindly is often unnecessary Understanding the power supply of the system is the foundation of proper KE-Jetronic diagnosis. In the next episode we move to the most important input signal in the system – the crankshaft sensor. #KEJetronic#MercedesBenz#Bosch#OVPRelay#ClassicMercedes https://www.paypal.com/paypalme/IvicaFyM Instagram:   / fix_your_mercedes   Patreon:   / fixyourmercedes   TikTok:   / mercedeskeje
