They like a good fully charged battery I would check the terminals are clean and tight,mine just clicked and wouldn’t start when the steering lock started playing up. |

Any 12v battery that is below 12.4v is going to strugle starting a car. Give it a charge & see what it comes up to. (Now Sold). 2008 Freelander 2 (Nazca Sand) SE TD4 Auto. Statutory write off & on WOVR for hail damage but still road legal.

Thanks for your reply. The car is starting everytime now??? I will clean the terminals after work but they look pretty tidy.

Sounds like your charging system needs checking out, 8v isn't even in the ballpark! Unless of course your multimeter is out of whack. (Now Sold). 2008 Freelander 2 (Nazca Sand) SE TD4 Auto. Statutory write off & on WOVR for hail damage but still road legal.

I would check it again - if the battery really was at 8V I doubt the engine would keep on running (ECU and injectors would give up long before that, I suspect), and it wouldn't have started in the first place. With the engine running you should be seeing something over 13.5 or so. The second earth strap is a good idea, and a likely solution to your problems. |

Your engine couldn't possibly crank over & start with that sort of voltage! (Now Sold). 2008 Freelander 2 (Nazca Sand) SE TD4 Auto. Statutory write off & on WOVR for hail damage but still road legal.

Ok thanks for your help. I'm going to order the earth strap tonight anyway and I'll pick up a new multimeter or battery tester tonight too. |

That earth terminal doesn’t look too good. |

Excuse my ignorance, but which one's the earth terminal ? I thought batteries just had +ve and -ve |

All modern cars are negative earth.

The negative terminal is also known as the earth terminal as that is the one that is connected to the car body. Almost all vehicles since around the 1960`s have been negative earth and most definitely if it has an alternator fitted. The battery terminals are marked + and - to show positive and negative and also the positive post is a larger diameter than the negative to help avoid connecting them up incorrectly. |

Of course the other thing is that it's possible to have a well charged battery and it reads normal at the terminals but if you have a poor earth or starter motor connection then strange things happen due to voltage drop where it's needed. Might just be worth checking if you multimeter is accurate though since they rely on an internal battery and a reference zener diode.
