Therefore the solenoid would click out however starter would not spin.. Giving the starter a tap moves the brushes ever so slightly and sometimes creates a good enough connection to spin the armature..
The best option is to remove the starter and take to a auto-sparky to be diss-assembled and tested for the best course of action
