Fitted a new battery the wrong way round for a second. Realised my mistake and installed it correctly.

Now the car won't start or turn over, it just clicks when I turn the key. The lights, fan etc are working.

Is there a step-by-step process I can follow to find out what damage I've done and how to fix it?
Thanks.
 
do you know if the battery has to be coded into the ECU at all, I know various cars have to have the battery setup !!!!!!!, my 14reg audi had to have a this done, just incase it happens to be that

Is there a bank of heavy duty fuses attached to, or close to the positive battery terminal?
Check these first.

Hello John,

Yes, there is a fuse box next to the battery. See pic.

Do I check check the small rectangular ones with a multimeter and the square purple ones by eye?

Do I need to check the black square ones at the back?

Thanks

Sorry, I don't know what that means.

That’s only for the charging rate to be reset. That in itself shouldn't affect the starting side of things.
 
Think there are 2 locatiosn for fuse box, this vid shows main location under bonnet and one is in the , the vid is for left hand drive but location is similar. You should be able to pull the smaller ones out to see if any ar ebroken:


I blew a fuse in sept on mazda6 when changing a part, teh fuse was located under the dash of footwell front passenger location.

good luck

The black rectangular things are relays, and likely to be ok.
All the other things with a number are fuses so remove each one and check them visually.
Be lucky!

Is the battery fully charged?
Your symptoms are typical of a flat battery......
