Hi all out there..
I have been searching for a year on and off for the reason for my battery drain..Checked many things..as you would expect..

However while changing my roof hoses and rear seats were removed, I spied an elderly "Car Tracker".. I ignored it, and just chuckled..
6 months on, I mentioned to an engineer who designs this stuff and he said, oh "that old"....Argh..
It will be eating your battery, very old tech..

So yesterday, in the cool sunshine, out came the rear seats again.. and there it was nestled next to a large ECU (body processor?) behind the seat back..

A small plastic box 2 1/2 inches by 4 inches(remember those?)

Anyway, battery off( I fitted a switch, as fed up with flat batteries!), I then disconnected it..

Next I connected my trusty "Avo 8" on 10 amps current setting, in the battery feed.. locked the doors.. and now rather than stopping at 500ma after 20 minutes it was down to 25-30 milliamps --Hurrah! I had to change to the 1 amp setting to see the drain..

A real result.. So certainly well worth checking if you have an old one fitted, or certainly checking as you may not know it is there!!

Good luck all

 

You can purchase a Bluetooth monitor which allows a smartphone to show current voltage and charging rate etc
I found this very useful

That module behind the rear seat back is the factory fitted phone module. It should still work if you have the handset.

 

Ah so the one is the phone unit? Wow I wondered what that was. Sadly so out of date in UK, almost no 2G here now!
I wonder if it is also worth disconnecting? One less thing to go wrong! But I assume it is integrated with the sound system?

 

That's not true. I have a 2G phone, and it still works everywhere. 3G has been turned off, but 2G has a few more years in it.

 

Ah yes I had not realised..Probably searching as the sim card was not working.. Anyway a bonus all the same!
