Hi Guys,

2005 Range Rover Sport that I have had for donkeys years and love it, really dont want to get rid of it.

Something is draining the battery when the car is switched off, after 5+ days of sitting unused it wont turn on. Had an auto electrician out today and tried a few things which has hopefully fixed it.

But if not, rather than spending loads, he suggested a solar charger in the cigarette lighter would make enough amps to counter the prasitic drain.

I know some cars shut down the 12v cigerette lighters totally when the car is switched off and wont even accept a charge going into it..... does anyone know if this applies to a 2005 RRS? It would be awesome if I could trickle charge it via the ciggy lighter but dont want to spend money on a solar panel if the cars going to lock down the lighter socket after 5 mins. -[RRS 4.4 v8 HSE ]-

If you have a mobile phone charger that fits it and has a light on it then use that to test
The boot one may be permanent live on your model year but maybe search on here  Visitor from fullfatrr.com

No. You need to do a mod.

It’s
Documented on here.

Plugging in a link on the fusebox

You can get a solar charger which will plug into the OBD port. The connection is permanently live (certainly on my 2008 RRS) so no mods needed. I think my one is from the AA.

Oh, and by the way, Dr Robs test suggestion is a good one but make sure the car has been left for 10-15 mins or so as I seem to recall seeing on here that some systems stay live for a bit after you switch off, then shut down. Robin
