For any electrical item on a car to work properly it must form part of a circuit. The starter motor needs a huge amount of electrical energy for it to function properly.
If the 'ground' or 'earth' connection is poor due to corrosion, poor contact or if it has worked loose and fallen off, then the circuits ability to supply enough power to the starter motor will be reduced and the starter will now work properly,
