Hi dear forumites, my beloved 1998 Atoz won't start. Happened for the first time 6 days ago, I turned ignition key and utter silence happened. My friend charged my battery with her compressor charger in 2 minutes, and off we went. Then I didn't drive for 2 days, and now when I turn ignition on, there is a noise like a jackhammer / machine gun coming from the battery area. I have removed and cleaned the battery terminals, which has had no effect. My Atoz MOT is due in a month , so I don't want to spend too much money now then find out she won't pass unless I get expensive work done on her. I have lost the handbook at either the \mot centre or mechanic last year, neither will own up. But I am logical and can understand most stuff if clearly put. Many thanks in advance for any advice.
