There is no connection to 86 on the relay to the right.

It needs to be grounded, if anyone is going to use it.

Fine, lovely will you stop making 86 the neg side of the bloody coil? When the Germans first used those relays in the 70s they had the DIN number codes for everything, later become ISO motor industry codes which is why say ABS or airbag or parking brake lights look the same on every car, that's how we get the relay numbers, other things like power side 30, lighting 55 on, ground 31, Ignition 15 etc etc

We received the Relays but the documentation must have fallen overboard.

Ah some one else as anal as me! Sorry about being pedantic but you're the ones who crashed a Martian lander because the software mixed up metric and imperial....... latching relay with 2 seperate switches - Page 2 -- posted image.

I can not go by that documentation simply because it states Pin 30 is the "INPUT" from battery and Pin 87 is simply "INPUT".

How can that be possible, since they are connected wouldn't one of them have to be an output? Silly Germans.

Haha

Craig, Kevin what have I started now? Can we all take our tongues out of our cheecks and admit 87 and 30 might be interchangeable? Convention on original non changeover relays i.e. 4 pin no 87a was that 30 was input and 87 was output, of course as an immob or change over for use in locking...we have 30 as output and 87 + 85 or 86 depending on polarity as input. OK I promise to stop being so pedantic in future.

I'm am willing to admit it as long as you are willing to admit 85 and 86 are interchangable!

All kidding aside, that document was pretty informative - I never realized there were "standards" covering the pins.
