connect negative lead first and remove it last ! , always connect direct to battery on good vehicle but ideally to earthing point on bad vehicle, leave engine running whilst connecting.

Well, the LR answer from the manual is:
Both vehicles off. 1. Connect +ve claw onto +ve terminal in donor vehicle 2. Connect other end +ve claw onto +ve terminal in dead vehicle 3. Connect -ve claw onto -ve terminal in donor vehicle 4. Connect other end -ve claw to an earth point in dead vehicle 5. Start donor vehicle, wait few mins 6. Start dead vehicle, wait two minutes. 7. Turn off donor vehicle. 8. Undo leads in reverse oder of above (4-1). Land Rover appear to have missed a stage: 9. If the dead vehicle was a lesser 4x4 charge the owner £20 for services rendered. |

It's very easy to touch or brush the bodywork with one of the jump lead claws when connecting up, and that is the reason for the stated recommended order. If you did it in a different order you could easily end up shorting out the battery via the bodywork, which is not only dangerous but could leave you with two flat batteries.

Anyone tried rigging up something like Entreq's jump start kit?
http://www.entreq.de/products/electrical-e...r-td4.html The father-in-law's tractor does not have a battery fitted (as it is used in frequent) and so needs jump starting. Somthing like a socket fitted to the outside of of the Landy looks a simple solution. Just need to do it to a tighter budget! JK No the other left . . . |

I made my own to save a little
Anderson socket placed at the near side of the bumper. I am forever jumping vans and FLT's.  Click image to enlarge |

Ive always connected the -ve clamp to the dead cars -ve battery terminal, not the earth point. Is there anythng wrong with doing this?

I believe the reason is that, theoretically, there could be explosive gasses (hydrogen?) around the battery. When you make the final connection you often get a spark, need I say more...! That said, I've actually never heard of a battery explosion, but I'm sure someone will know different! |

Not sure its the same with LR, but I know from work that if you jump start a tractor (either the doner or dead vehicle) straight onto its battery terminals it can fry the ECU and/or engine CPU, and I've seen it on three different tractors myself. This is why tractor manufacturers now put in designated jumping points to use and warn customers not to jump straight off the battery. |
