Ok been reading up, some misconceptions by myself, but slowly getting there which is actually fun aswell & as sad as sounds exciting lol.
Now I think I need to use a polarity conscious switching component inline with the motor feed wires so effectively in parallel with motors, as it obviously reverses polarity on the motor wires to make the motor change direction which is how the locks work (pic to follow possibly), so I could use the polarity sensing to trigger my 555 timer relay circuit, so surely a relay would suffice thats polarity conscious, not bipolar I think is the term.
The motors arent in series mate, the common wire isnt between them, it comes from further up line namely control module, then branches of to 1 leg of each motor.
Am I finally making sense fella?
Thanks for the info btw, it all helps trust me even if it one way flowing atm, no pun intended.
Also now I understand the braking you explain which actually does make sense & could apply to these, urrrm more knowledge gained.
