   Noticed there was no power to my headunit on way home from college, went to lock my car but the fob wouldnt work and also the rev counter doesnt go back to 0 when i turn the car off.
   
   Also the clocks dont show time etc when the key it turned 1 click.
   
   Any ideas?

   Either;
   
   A) Alternator isn't charging properly.
   B) Battery isn't holding charge.
   C) Damaged alternator wiring.

   Recently had my cambelt changed and noticed that my alternator belt had a crack in it.
   
   But it still seems to be running fine...
   
   I think it may be the battery since its a tiny battery for a car...
   
   Hmm...

   Don't assume, test the alternator.
   
   It's a piece of piss.

   Seems like it's charging fine, next thing could be battery.

   Hmm.
   
   Might just have to get another battery in that case. Will try and get it tested.
