Constant power to 12 volt

My wife just purchased a 2008 RR SC. On my 2009 RR Sport I was able to bridge 2 fuses to give constant
power to the lighter plug behind the center console. Is this possible to do this on the full size and which fuses would I buss?
Thx!

Do you not have the accessory socket in the cubby box that's constant 12V?

Alternatively get a multimeter and test which fuse is still live - This is a terrbible bodge way to do automotive electrics as it bypasses the fuse for both circuits if you are crossing circuits.

But either way is up to you Thumbs Up

Without checking wiring diagrams so that it is absolutely clear what happens when you jumper the fuses, that's more than a simple bodge - it's a real potential for problems. Power flows both ways, so by jumping power from another fuse, you're potentially putting constant power across any one of a number of fuses that feed off the same spot the bridged fuse feeds off. At the very least, you're risking a dead battery. Add in something that draws heavy current from one of the other fuses on the feed and a thin jumper wire and it could even become dangerous. And, are you even sure of all of the rest of the items being powered by the cig lighter fuse?

The only clean way to change something like this is to switch power sources - either by swapping the wire to the cig lighter to a constant 12v fuse at the fusebox or adding a fused 12v source.

If you are going to the boot then on the right hand side fuse bard there is a big fat contstant 12v feed in there you could tap off of.

Got to agree jumping fuses WILL eventually cause problems.

Find another permanent live ie cubby box or rear 12v socket and perhaps run a feed from it and disconnect the old feed. TDV8 HST Sport **Current**

Hi all, If you go to www.rrsport.co.uk/forum/topic12783.html
it shows how to put constant 12v power to rear seat cigar lighter.
I did this on my sport and would like to do it on my wifes new
FFRR. does it have the same fuse configuration as the sport?
Thx

Jumping a relay is a different story than jumping fuses - although same goes here: you need to know which circuits are getting power as there may be more switched on continually than just the cigarette lighters and you'll end up with a dead battery (why are they called 'Cigar Lighters' in BritSpeak - Churchill? Or is it the car: RR's(both kinds), Astons, and Jags have 'Cigar Lighters' whereas a Ford Mondeo has a 'cigarette lighter'? Razz ).

I only have the wiring diags to the <06 models avail in RAVE. You'll need to find someone with access to LR's online GTR to access the later diags to answer this question.

In the Owner's manual they refer to that particular fuse as cigar lighter??
