Hyundai Atos GLS that does not start

To whom it may concern.<br> <br> I have had issue with my Hyundai Atos GLS that does not start for the past week.<br> <br> I have contacted the Service centre in Paarl and spoke with Ulrich, the Workshop manager.<br> <br> It looks to have been the Negative connection that connects to the battery that gets loose and then not charge the battery correctly<br> <br> On Friday, 24.07.2015, i got the car started and when to the service centre. It was tested and the loose connection is the problem. It was tightened and I could drive the weekend, but Monday morning I could not start it again.<br> <br> After a long struggle, the car started with another battery and then I went to the service centre again. this time I left the car with them from 12:30 until the next day, the 28th, at about 15h30.<br> <br> According to Ulrich the battery was charged and tested 100%, so the issue should be resolved.<br> I managed to start my car twice without issue before it did not start again. I notice that there was a ***** added inbetween the connector and the battery contact and that the connection has also loosened. after I tightened the connector, it started once.<br> <br> It did not start again. I need help with this Please!!!<br> <br> Alwyn Grobbelaar
