So my battery is totally flat, got it jumped then about 1hr later it drops down to under 12v resulting in not being able to start it again. So there's something drawing the battery but can't find what it is.(got the battery checked at halfords and it shows its fine just draining). I have taken the boot light out,turned all indoor lights off,headlights off and radio off but it's still draining. What else can it be ?
Also when I left the car on the coolant basically overflowed spattering everywhere and engine temp went in the red could this be not enough power getting to the fans also ?
