Help GT Battery Draining Problem

Hi I have a GT 1.9 JTD 2005, I am having a problem with the battery draining when I have not used the car for 1 day, I had a problem with this last winter took it to alfa dealer they couldn't find anything wrong with it, it seemed to sort itself out, (as alfas do). But its back again the AA say the batteries fine, I can't afford to take it back to the dealer now the warranty has run out. I use the car 6 days a week and average 60 miles + daily, we have boot light, rear lights, front lights, internal lights. they all seem ok. Can anyone help me?

Re: GT Battery Draining Problem

Check the main earth connections and terminal connections - one of them might be slightly loose.

Re: GT Battery Draining Problem

My only suggestion would be that it could be the radio/cd player causing the battery to drain. This happened to me (only when I left no CD in it), and in fact would STILL happen now if I ever left the CD tray empty.

Here's a link to my old thread on this subject: (GT - does your radio ever turn itself on??) - although this wouldn't explain why you're only getting the problem in the winter, and you'd probably have noticed if your radio was turning itself on!

So this is probably of no use at all, but good luck getting it resolved anyway.

Re: GT Battery Draining Problem

Boot lid switch? light in boot stays on when the door is shut and runs the battery flat?

I am having exactly the same problem with my GT (2004 plate). It's been in the garage twice. The manufacturer's stereo seemed to be causing the problem and the garage replaced it with a non-alfa one and put in a better quality battery, this now gives me about a week of charge, but every time I go away and don't use it for a week or so the battery is dead when I get back. Alfa specialist is stumped and his advice is to disconnect the battery if I am not going to be using it for a while.

I love alfas and this is my second.......I'm seriously considering not having a third.........

Alfa GT

My 2006 GT has been doing the same for the last 2 years. It has been back to the dealers 3 times and to a specialist electrical company. They can find no drain yet a week later it does it again. I suspect the electric window motor as this was repaired then replaced in the first year I had it. As long as I run it regular its OK but left a week and its flat. Apparently the radio can turn itself on as well which is cured by leaving a CD in it. I have admitted defeat and trickle charge the battery once a week. Good Luck

Exact same thing has happened with mine. Does the 'cured by leaving a CD in it' thing really work? I was thinking about disconnecting the radio/cd unit, or just removing the relevant fuse?

Also, has anyone ever used one of these jumpstarter packs: Halfords | Dynamic Jumpstarter

Or are they as bad as they sound? Trouble is, where my car is parked requires about 12ft jump leads.

Have you tried locking the car with the key rather than the fob?

I've found if I lock the car on the fob and go away for a couple of weeks the alarm seems to rip the life out of the battery, but if I lock the car with the key it's fine.

I wonder if they can test for drain with the car locked on the fob and then again on the key to see if your alarm is causing the drain.

GT JTDM Alfa Red

Had similar problem 3 months ago on my 2007 GT . Extensively tested the vehicle's electrical system for excessive power drainage on each occasion with no faults apparent . Tested the battery which appeared initially AOK. The fault was finally resolved when I actually replaced this battery

You can try to find the source of power drain with a cheap multimeter capable of measuring the current in mA (not voltage in V). Without ignition on just open the fuse box and go methodically fuse by fuse. Remove fuse, connect multimeter and see if there is some drain through it. If there is 0 mA, the electrical device connected to this fuse is not consuming anything. If there is some current drawn through - the device on this fuse has some consumption when ignition is off. Check fuseboxes in engine bay and under the dash and eventually you might find though which fuse (device) is the current drawn away.

It takes time, but you will eventually find the spot where you have electricity "leak".

An old battery can often be the problem. It seems to be OK, takes a charge when you drive regularly, but loses it if you don't use the car for a while. Duff batteries can seriously confuse modern car electronic systems - throwing up random error messages from sensors and the like. If your car's five years or more old and on its original battery, chances are it's on the way out and needs replacing.

Various Alfa's

rule number one dont trust anything an AA man tells you, get the battery tested properly with proper equipment they might have just done a voltage test which will not tell you if you have a defective battery, if this is ok a proper test needs to be carried out to establish if the car has an excessive parasitic drain if you dont know how to do this take it to someone who does, simplest way is to close all the doors key out of ignition, remove negative battery terminal and connect a multimeter set up to measure amps one probe to the negative terminal and one to the negative lead and secure them with tape of something, now let the cars eletcronics enter sleep mode after give it about ten minutes to be sure now see what the papasitic drain on the battery is, the maximum of 30 mA or 0.03amps if you have more than this then you have to find out where it is coming from by a process of elimination, disconnecting things while watching the gauge, if you find you have a drain first thing id be disconnecting would be the radio as had a few cause a problem.

had a similar problem with my 2002 facelift interior 1.8 alfa 156. i replaced the battery and problem still existed. the car would last maximum 30 hrs before battery would be too drained to even open the doors. tried everything , testing for battery drain, checking rear lights for faint light, boot light. without knowing about it i replaced my cd player for a non alfa one and no more battery drain. the longest the car has been left locked now is one and a half weeks and starts no problem. either replace cd player for another alfa one or just go after market. im 99% sure this is your problem.
hope this helps u. cheers

See the link I posted last year in post 3 of this thread above! If you have a faulty radio/CD unit then it definitely works, for me at least. Leaving a CD in means I have no battery draining issues (I can leave the car for 2 weeks and it starts without hesitation), but if I leave the car with no CD in it I can guarantee my battery will be flat overnight as the radio will have come on when the car's locked up.

I've had this minor inconvenience for 3 years but am too much of a cheapskate to replace the CD unit.

Exactly the same here, and my GT is the same age as the OP's. One thing to add - if the battery gets low on charge for whatever reason (too many short trips, battery a bit old and tired, etc), then the radio/CD appears to start of its own accord, whilst you're away, EVEN IF a CD is inserted. But with a decent battery, leaving a CD in does stop the problem. It's definitely the first thing to try.

Battery drain

I work in the mines 1 week on and 1 week off. My battery is flat every time I come home after a week. My radio/CD does not turn itself on but my air conditioning does. I turn it off when I stop the car but when I get back in the morning and start the car the air con is on. I can hear the fan speed varying too when I drive. Anyone experienced this? I'm wondering if this is my battery drain issue? 2007 GT V6

If you lock the car with the key as in the handbook it suspends things it is designed for long term park up.
One thing to check as you cannot see them is the sun visor mirrors they have lights and if the flap doesn't close properly or the switch is faulty they can be on without you noticing
