here is a post of mine sorting out some electics with the starter and ignition diodes.

One of the starter diodes is faulty with the same resistance both directions.
i had also accidentally swapped then over after testing, pushed the start button and for a split second i thought i could hear the starter moter turn then starter relay started clicking.
2nd start up even less starter turn then clicking
3rd startup as expected no stater turn but still clicking
So that should now be pointing me back to the 11.5v battery issue
