Just replace the wire and report back with what happens.

Sell replacement connectors and pins, if you don't replace that connector it will come back to haunt you at a later time.

OK.  Loose white wire resoldered back on to middle right scoop (diode side)....Nil change.

With a clear head this arvo (been thinking about this prob all day!)...realised one thing...The scoop spinner is causing phantom's (or is it contributing)....Realised that I have 6 active switches as well (ball trough)....Removed all balls, trough 3 seems to be a culprit.....

With Trough 3 activated, scoop spinner activated problem occurs....  With trough 3 off, spinner on and both flippers activated...Nil prob...

I have swapped switch (with diode ) with a spare...Nil value..
