Hey folks got a problem the battery is farely new about a year old and is getting drained after a few days maybe even after a day. The car doesn't get driven much and when I'm Offshore gets disconnected.

It might be the battery but also want to check the alternator I have a multi meter what connections do I go to?

Thanks

Steve

 

Have the car running and go on the battery terminals you should see about 14.5v.

 

What model car?.

 

Has it got a tracker fitted.

 

2.5 hawk sti

Don't know about the tracker tbh

Measured before car was running 11.7 volts

Measured 14.5 volts when the car was running

Steve

 

well alternators fine, battery voltage is a bit low might just be fatigued.

What ancillaries do you have: like after market ECU/ alarm system ect as you must have excessive current draw when the car is idle. From what I can remember the average car draws 0.03 of an amp in hibernate. You will have to check the spec for your current model and you will have to check the current draw once the car is in hibernate. about 15-20 mins once you have applied the dead lock.

please see: I would explain but take too much typing.

 

Cheers for the info checked this morning and the current draw I am getting is between 0.09 and 0.11

I began to remove one fuse at a time low and behold by the 4th try I think I found the problem

Sure the fuse in question is alarm / central locking

Steve

 

looks like you may need a new alarm control unit. it seems it not going into idle, is it the oem one or an aftermarket one.

what you do offshore anyway?

 

Oem. One I'll just buy a new battery for the time being and remove the fuse and manually lock the doors

It gets washed more than it gets driven lol

Bridge crew nothing fancy

Steve

 

well you might as well hold off on the new battery give the old one a full charge and see how it holds up with the alarm fuse out. as batteries aint cheep.

bridge crew does sound fancy who u with.

 

It's no really and maersk

I've bought and fitted the new battery and removed the fuse will give it good run later

Cheers for all the help

Steve

 

my car does the same thing, battery is fine and charges correctly, if i remove the same fuse as you have mentioned it doesnt drain.
i have done a test on the car and there is nothing draining the battery so i can only assume its the alarm control unit.

 

Cheers tubbs for the info I've removed the fuse for the time being as it won't be getting used on a daily occurrence

Steve

 

thats what i do now, not ideal but the car doesnt get used for weeks and its the only way to stop battery going flat.

mine started a while back and i hadnt fitted anything electrical so it has to be alarm related.

had a search on the net and it doesnt turn up much though.

 

Oh yeah I often work on the Maersk vessels, what one you on.

 

Oh Cool been on a few, the assister and most recently the Emma maersk

 

ah the assister the sister ship to the responder.

You gotta be changing your usernames more often make it a bit tougher to figure out lol i sound no worries got a few days in me back pocket so dont need to be heading off anytime soon

I was thinking this guy knows his batteries probably cause hes had some form of german scrap in the past
