few words of advice!........

had this problem with my run around car....battery was lasting 3 days MAX before dying....brought a new battery AND Alternator and still had the problem...

ended up being the EARTHS on the engine/chassis they had all come loose hence making a shat connection... out came the socket n rachet for a tighten up n haven't had a problem like it since except being 150 quid down for something that could have been fixed by spending nothing.

HTH
