Forums Forums Enthusiast Forums A - Z Autowirral A Rav 4

Hi does anyone know of a mobile engineer that can do diagnostics,the problem is a brand new battery on a Rav 4 M reg car about 12 year old and after two days the battery is completely flat something seems to be draining the battery,its kept in a garage.we have to leave the battery off until we need to use the car.

I'd start by checking the basics - take out the boot shelf if it has one, to see if there's a courtesy light not going off.

Next I'd try disconnecting the stereo.

Start by pulling a few fuses for "courtesy" items like the above, maybe the cig lighter, alarm and so on.

It doesn't cost anything and may save you some pennies if you can pinpoint the fault.

Have you had a look on the Rav car forums to see if anyone else has had the same problem?

Thank you for the answer,this is my husbands car and unfortunately he is in a nursing home,it needs to go for an mot so i can get it sold, i will get someone to try what you say.thank you for your time.

May be the alternator Meem. Is it dying even when it is left?
I can do a quick test if you get stuck - will soon find out whether it is or not.

Silly one ,check the leads are on properly sounds silly but it can cause the problem

Thank you so much i will tell my daughter tomorrow,will keep you in mind if its ok with you.

Thank you first thing we checked,that is ok,it is something that is draining the battery.

Long shot, but it could be a faulty new battery.

Hi Gibbo, Thanks for replying when we bought the battery and it went flat we phoned up to ask could it be a bad batch,they offered to replace the one we had and see about the one we took back.
After a couple of days they phoned to say no the battery recharged had it on a car no problem and sold one to another customer who has had no problems.

I had a motorbike with a similar fault, in my case it turned out to be the alarm which had become faulty even though it worked as it should have. Disconnected the alarm via its fuse and the battery stopped draining.

thank you Geemeister,Will try that
Thank you.
