wiring looms, airbag module, alternator, possibly some other stuff too, not good dude.

Gab

how have u installed the battery the wrong way that it has damaged stuff??? are u meaning u had the positive and negative around the wrong way???

have you checked for fuel and spark ?

fuel pump priming ?
screw driver spark test ?

ignition coil probably nackerd!

coulod it possibly be that the smart lock is not likinbg the bcm????...and if so how do i do that with the windows up...or do i sit in there for 30mins to get it to circulate....and arent the windows meant to work if thats it...or have i fried the smart lock ????

hasgas and fuel same on both ...so id say ignition...which could be smartlock or coil as suggested....buty still loits of other stuff not working either

spot on...cant believe i have done it...trying to go to quick doing too mnany things at once....

first thing u do dude is check all the basic stuff fuses , negative and postives cables the fact ur windows are also not working id be checking fuses first then reset the ecu

Similar thing happened at work, one of the salesman jumped started a rav 4 the wrong way and blew 5 different fuses and I had to fix the thing. Have you checked all your fuses? Even the main fuses under bonnet? And as for the air bag light what code is it flashing? The code is displayed by the number of flashes e.g flash............ Flash flash. The first one is 1 and the second is 2 so the code is 12 which is a low battery voltage code. You can reset these codes by earthing out the 4th pin on the top line of the diagnostic connector located in the fuse box at the drivers right knee. If the codes don't clear then you wil have blown the airbag fuse. When replacing airbag fuse disconnect battery for 1 minute to disable the airbag system. When earthing out the pin it will beep 5 times consecutively to indicate the code has been cleared. If it keeps blowing fuses and throwing codes then you might need a new airbag module....

As for the starting problem. Check the 3 things. Fuel, spark, or something mechanical. Doubt it will be the last though. A multimeter will help you diagnose it easier so you can check for power when operating the power windows if you've allready replaced the fuses for them.

Hope you haven't fried any wiring...

thanksguys got it sorted tday....i kmissed the int liught fuse which i thought i had replaced but anyway once i did that all i had toi do was relearn the bcm and viola....away she goes....

only thing thats not right is that the airbag light comes on flashing 4 times i think....and the abs light as well....

i will sort through it but any ideas still further appreciated

This is an easy thing to do when f*&^head Ford designers decide to fit batteries in different models that have opposite polarity - ie. in your ED you have neg near the pwr steer but the battery in EF has pos that side - but otherwise the batteries look nearly the same and are same size etc.(rolleyes). I've NEARLY been caught out myself.

Also I have no idea why the motherf*&^ers went from bolt thru post to USELESS f*&^ing clamp on type terminals - never had dramas with bolt thru type but the clamps on my EF are a constant headache. I'm gonna drill the f&^%ers myself and put 3/16 bolts thru!
