transit connect strange battery drain problem

[AlanHarrison]

Hi Guy's.

I've got a 2007 transit connect and having a strange battery drain problem.



When the weather is mild (warm) and left overnight it starts perfect, however when the outside temperature is cold, it drains the battery.

I've done a battery drain test in the day and all seems to be OK, however I can't stay up all night to keep testing the battery..



I would appreciate any help or advice.

yes guy's, I've had the battery tested and all is OK.

I've also disconnected the battery and reconnected it in the morning and its hold a charge & starts first time, I've also had another battery connected overnight.

Thanks for the input & any other advice would be appreciated.
