My freelander
I asked a mate who knows nothing about cars to put my battery on.And yes pit it wrong way .So now put fully charged battery on it and its flat within mins.I thought alternator or starter so I disconnected the live feeds to them and still the same
No fuses gone I don't know what can do to find the problem .the rear window did go down then not go up till fully charged again .
What is first on route straight from the battery as I been pulling fuses and it still happens.
Im based Nottingham if ne one near so gutted as had take off road to do mot now im stuck in till I sort this .

You have probably fried. The ecu, and the alternator,
