What does OVP relay do?
A the time, the best way Mercedes had to protect these items was with the over-voltage protection relay (the OVP relay). This setup allows a fuse to function as a voltage protector. It works by using a relay that monitors the voltage across the electrical system in the car.
How do you test a OVP relay?
Testing OVP
- Ignition switch OFF. Unplug the connector, use a test lamp or a multimeter check all the pin from the connector for power.
- Ignition switch on.
- Testing the relay:
- Ignition switch ON.

What is the voltage of the overload protection relay?
Tech Tip: When checking voltage at the pins of the overload protection relay pin 30 is hot with the key on and pins 87 are the output voltage to the control units. If the relay is blown there will not be voltage present at pins 87. ”
What does OVP over voltage protection stand for?
OVP Over Voltage Protection. ERIC. PC, aka, Political Correctness, is a doctrine, fostered by a delusional, illogical minority (Liberals/Socialists) and promoted by the mainstream media, which holds forth the proposition that it is possible to pick up faeces by the clean end. Ah, the short answer.
