Dead battery

[Malcolm_D]

Used the car on Thursday and apart from a misfire on pot 5 it was fine. Have not used it as I was going to sort misfire before using it again. The only other issue I have had is that the wire for the reversing lamps snapped where it is connected to the boot hinge.
This morning it was as dead as a dodo, wouldn't even open. Got it open tonight and yes, the battery was totally flat! Why? Nothing was left on and the battery is less than a year old, alternator is also new 3/4 years ago.🤔

Have you removed the power-sounder?

If the answer is no - have you heard any peeps from inside the scuttle at the base of the windscreen?

No and no, I don't recall hearing any. Have read up about the dreaded powersounder and will look into it. Thanks for the help.

Another possibility - does the centre of the ignition switch pop out when you remove the key? If it stays in I believe various items remain powered when they shouldn't.
