Use a 12 v supply can be the 12 v from your car with about 200 ω in series. Bosch relay guide 15 pdf drive search and download pdf files for free. The tycobosh relays have a rating stamped on the cover that is based on switching 30 amps for over 250000. If you get over 1 v in one orientation and under 1 v in the other then the diode is working. I thought that if a diode was across the low voltage coil windings of the 85 and 86 terminals that they would be polar sensitive.

This collapse causes a voltage across the coil in the opposite direction to the voltage that created it 12v and since the collapse is so rapid the voltages generated can be in the order of several hundred volts although very low current.

When voltage is removed from terminals 8586 and the coil is de energised the magnetic field that has been created around the coil collapses rapidly.

These high voltages can damage sensitive electronic devices. The freewheeling diode allows current to pass with minimal resistance and prevents flyback voltage.
Bosch relay guide bosch relay guide bosch relays. Quick application guide bosch relays. The diode will limit the voltage drop in one direction. When the power supply is removed the voltage polarity on the coil is inverted and a current loop forms between the relay coil and protection diode. Relay with diode across the coil.

Placing a diode across a relay coil passes the back electro magnetic field and its current through the diode when the relay is energized as the back emf drives the flyback protection diode in forward bias. Briefly connect this to the relay coil in each direction and measure the voltage accross the coil. Such that the coil would only activate. The diode again becomes forward biased.
