Fehlersuche am Relais und Relais Prüfen

Here I will show you how to troubleshoot the relay and test the relay. Set values ​​of a relay in the automotive sector: Relay coil terminal 86 to 85 = 40 -120 ohms Relay switching contact terminal 30 to 87 = 0.0 ohms If you measure a value in the kiloohm range on the relay coil, the coil is also interrupted. Your relay then has a quenching resistor built in and this is always around 1 kiloohm. The quenching resistor quenches the high voltage (around 1500 volts) that is induced in the coil when the magnetic field collapses.
