Car Wont Start After Radiator Replacement.

[ametcalfe1989]

Hi guys!

 

I've just replaced the radiator on my GV 2.8CRD.

I realised after 15 minutes I hadn't disconnected the negative terminal but by this point I hadn't touched any electricals.

 

Now after the replacement I cannot even get the car to crank, it just clicks. Battery is reading 11.8v.

 

Could i have shorted the battery? Done something to the immobiliser?

 

I have pre ordered a battery from Euro Car Parts anyway as they were half price and my battery is from 2017 but I just wanted to make sure I wasnt missing something stupid before I go and replace the batt.

 

Any advice welcome

Yep at 11.8 volts it's as flat as a pancake!

 

Have you got a charger for it to try?

Tried charging for 12 hours and it went up to 11.9 haha!

Was definitely the battery (thank god for Eurocarparts New Year Sale!). New battery in and started right on up!

The plonker owner before me had swapped the positive connector side to fit a battery the wrong size in so it was a pain in the ass to put right but once connected all was good

 

Now I'm just hoping for no leaks of the coolant over the next week or so

@ 12v you've got only 25% in it

@ 11.8v you are 0% as Nev said flat

 

You can subtract a lot of CCA / voltage at current UK temperatures. I'm a ecumenical about big 800/80 big batteries on 2.8 GV's but the won't fit without moddin the battery tray and a very salty price point.

 

The Optima 'RedTop' Spiracell battery - 12V - 50Ah (815cca) is always a good starter battery. YOU make sure it will fit your car and the terminals are the right way round my friend.

 

A brand new pair of linked £600 each batteries will not stay charged if you don't give them frequent long enough trips. Lifestyle (lack of use) is a big killer [flat/sulphates] of GV batteries.

 

Best of luck.
