Is there anychance of saving it?
or
Should i buy a new one , if so is it worth forking out for a new one or would an off the shelf one from repco or the like do the trick?
Had a brief serach through the forums on here learnt about "cca" but still have no idea what im looking for

also there is a few random wires coming of the positive terminal looks like they go to the lights any chance it would be causing it to drain?
Cheers
