06 fabia vrs no turn over fixed

Just a heads up. All of a sudden mine refused to turn over in an Asda car park last night whilst out shopping. First thought was the thin wire going to starter solenoid as most people suggested. Upon inspection mine was already fixed previously!

Turned out it was the EARTH lead from starter motor to chassis - directly under the battery tray. Totally worn off at the end. Cheap and easy fix!

Furthermore, although engine started with a push, the traction control and oil pressure light illuminated and beeped all the way home so the poor earth triggered that too.

Not much info on this so I'll put it out there as the alternative solution.
