Hi all,
I have wired the diagram as below and tested.
I get the latched on but the next pulse does not unlatch the relays.
What have I got wrong and how to fix it?
Is there something amiss with this diagram?
Any help appreciated.
Thanks

Double check that each of your relays are SPDT relays, verify placement/direction of diodes, and that your connections are solid.

Hi, Thanks for the response.
I have actually used DPDT BT type 47 relays on a PCB.
Only using one side of the relay of course.
The diagram I have used is here.

I have not tested my configuration/diagram using DPDT relays, though in theory it should be exactly the same. Without having one of your relays to test, I can't say for sure what the issue may be. I'm on my phone at the moment and did not verify your diagram, but will attempt to do so when I can get on my laptop or desktop.

Your diagram looks fine.  

Here are a couple things to test once it latches on:

Check that 87a on the first relay (far left) has 12V+ and the other relay connections on that wire do as well.

Check the operation of the fourth relay (far right). This is what kills power to the latched relay (middle left).
