L322 Changed battery - car won't turn over!

Hi guys,


I've made a monumental error. I accidentally put the new battery in the wrong way round.. connected up and lots of sparks, all the electrics went haywire! Headlight washers, windscreen washers, horn, the lot.


Battery in the right way round.. car locks & unlocks, interior lights come on but the car won't start. Doesn't even want to turn over.


Assuming immobiliser issue?

I have checked all the little fuses in the boot, glovebox and engine bay - 3 blown in the glovebox, replaced but still no luck starting the engine.


Any help really appreciated.


And yes, I realise how much of an idiot I have been!!

Many thanks

Hello,

Well I think a good auto electrician might be your best bet.

But saying what version of the L322 you have , model year , Engine, might help as well.

Welcome , and hope you get it fixed.

Cheers

No worries, sadly I think this will get expensive.


Cheers

I seam to remember some one else doing this a while ago , and there was a big fuse in or around the battery box that had gone, i may be wrong but some else may remember more.

Found the thread unfortunately no real final fix but may be of help

We all make mistakes, hopefully a missed fuse. Is there a charge that pops on the red live wire to the battery like the bmws have? It may have popped or partially popped in the confusion?

Just an update to say that I have replaced the mega fuse in the positive battery terminal and the car now works! (Minus the heater control panel)

Glad to hear you got her running. Now just the heater to fix
