Battery drain traced but now got central locking failure


Recommended Posts

Dear all,

just a quick update on my battery drain problem, and I need further help please.

Ok I removed the passenger seat and disconnected the alarm module.

Put the multimeter on as described by toolpants and got a whopping figure of 460 miliamps

Went through the fuses one by one and lo and behold it was the radio that was drawing all the current as soon as I removed the fuse the draw dropped to 40 miliamps which I think is the acceptable figure for Boxsters. I plainly have a wiring problem but Ill investigate that over christmas, anyway needless to say I have removed the radio (Becker Traffic Pro) and have removed the fuse.

At this stage the battery is disconnected, the key is out of the ignition and I then start to reconnect things.

I put the key at ignition switch 1 to stop the alarm going off when I reconnect the alarm module, I reconnect the alarm module and reconnect the battery, the car starts ok, it runs roughly but I think it is because the brain has to learn about fuel etc all over again.

However, my electric windows don't work using the switches, they do drop down when I open the door and go up when i shut the door.

I then pressed the remote to lock the car and the locks engage and then disengage straight away followed by a quick double hoot of the alarm siren.

Is there some sort of reset procedure I have to follow given that I disconnected the alarm module, which I am guessing is linked to the central locking and windows.

Thanks for your all your help so far, at least I've traced the battery drain but now can't lock the car.

If you disconnect the battery, you will have to "reset" the windows. Just power them all the way down manually and all the way back up.

It's ok its all working again, the trick is to keep evrything connected then disconnect and reconnect the alarm module, everything is now fine, although when I put my drivers side window down the cable must have been frayed because it all got wrapped around the sprocket that connects to the window motor.

Ordered a recon regulator for £75 hopefully it will arrive on thursday- it never rains but it pours,

BTW Merry Christmas to all
