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

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! Dan |

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. |

with the amount of temperamental electronics on the range rover, i would take off both leads to be safe... |

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.

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.

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. |
