battery going dead please help

i have a l322 td6 and my battery keeps going flat daily, i have checked for a drain across the earths and its 12.45 volts, i have pulled every fuse and relay i can find and its still 12.45 dead short, anyone got any idea and are there any hidden fuses, i had trouble with my radio amp and took it out off the car and someone said it maybe cause off this

Heater fan resister
Blue tooth module full of water
Boot full of water shorting out turtle for the was
Cd changer stuck on

thanks for the reply and input mate , unplugged heater fan resistor no change, not fitted with blue tooth, no water in boot and i have disconnected the change, anymore thoughts on what i could check

how many amp is the drain? your refering to volts in your post. if you check the amp drain the figure will give you a rough idea for what to look for or what is draing your battery.

Rectumfrier in alternator going tits up??? That'll flatten a battery in no time

when i put my amp meter between my battery earth and earth lead the meter reads 12.45 and when i touch the earth lead back on there is a bit off a spark, how do i read the amp drop , sorry to sound so thick lol

Disconnect the alternator.

i tried it with the little black plug disconnected and it was just the same or do you mean take the live i.e big red wire off

Once the engine is cold put your hand on the alternator...if its warm there's your fault....if it's as cold as the rest of the engine keep looking!

good tip mate i will check that this morning cheers

Yep, sounds like the rectifier diodes in the alternator have gone short circuit. Often happens when welding has been done without disconnecting the battery.

Some alternators can be repaired with a new rectifier kit, but not sure if your's is one of them.
