Electial Problem.
May 17, 2020 (1 week ago)
Hi I have a 2004 Laguna, which has an electial issue with the battery going flat within 5 hours.
So I have replaced the battery and the problem still exists, So I changed the alternator then charged the battery back up, and then within 5 hours the battery goes flat again. There are no warning lights showing and the car starts and drive with no problem. Then changed battery to another new one and the problem still exists, it running the battery down really flat so that it does even show internal lights. Can you help

You must have a helluva draw on your battery if it drains in that space of time . Check for a parasitic drain .
