Charge it on the car, but disconnect the negative lead from the battery. This will hopefully reset your other issues too.

RR's can eat batteries, is the one that's on there a, genuine and b, the correct rating?

my local dealer says that disconnection of the negative should make no difference....
is there any particular feature you are disabling by disconnection of the negative?

No difference to what? No difference to your issues, or no difference whilst charging?

Disconnecting the battery is the widely accepted first method to fix any RR electrical issue...

One always disconnects the negative lead on a battery first - it's just how its done. When charging you don't want to stick the charging current into the car electrics - so by disconnecting the battery you break the circuit. Coupled with the fact the pyrotechnic charge lives in the positive lead and its generally a good plan to leave that alone!

just asking what difference taking the negative off makes. On all other vehicles that I have owned, I have fitted charging leads to the battery so when I want to recharge the battery, I simply plug the charger in.

a couple of questions please guys

how do you get the bonnet to go higher? do you have to take the gas struts off?

when disconnecting the battery, i read about the pyro blow you up thing in the user hadbook, but can you safely take the pos and neg leads off like you would with any other car? Current: TDV8 (3.6) RRS HSE

you can get the bonnet into service mode by removing the two gas struts and using the two metal clips to steady the bonnet in a vertical position.

leave the range for 10 minutes with the key out of the ignition before you dis-connect the battery .

There is no benefit to taking the pos lead off if you've taken the negative lead off as there will no longer be a circuit... All it means is you have to undo another connection unnecessarily and they are fiddly at the best of times. Whereas you can easily remove the negative lead with the bonnet in the normal position.

As per Scary - you don't want to introduce a surge through the vehicles electronics. Pretty much every car made today says in its handbook that you should not charge the battery whilst it's connected to the vehicle.

Personally I have charged the battery on the car, but only with a small 6A charger. Using any of the fast charge systems would be asking for trouble.

Now I have my second battery installed I no longer need to worry about this :p

It's always done for safety ! If you undo the positive first & accidentally hit any metal part of the car (or any other part that is connected to negative/earth) with your spanner it'll make a connection & you'll feel it !

Obviously if the battery is completely flat, then the risk is less, but on a fully charged battery you'll be amazed at the current flow you can get and sparks will fly. If you happen to be wearing a watch or ring and that bridges your spanner/positive connection to earth/negative on the car body, you will get a very nasty burn !
+ of course any sparking can case fires.

So this is the reason you should always remove the earth first.

There are rare occasions when you can come acrosss positive earths on vehicles - but they are rare and I think all vehicles after the 1970's were made with negative earths as that standard was introduced, but it's always good to check.

not sure how you did the cut and paste to say Rambles wrote "One always disconnects....".

But no I didn't.
