Battery flashed the wrong way round? Help.

Hi All, Not sure if I'm doing this right. In a bit of a rush and its myfirst post. Anyway, quick question was...Does anyone have the solution to a rather silly problem caused entirely by my own stupidity. (Rushing then too) Flat battery on Disco 2 V8. T Reg. and managed to connect jump leads wrong way round in the dark... Ooops! Have now got a battery cut off symbol on dash and no response with Key even with a good battery connected. Anyone have any advice? Assume I have blown a fuse or similar. Maybe worse and upset the ECU??? Help. Thanks in advance. TandG

sounds like you fried something

ooohlalala
reconnect battery correctly and trace the point at which you get no circuit with a volt meter by putting the positive probe on the positive terminal of the starting components, taking readings as you go, making sure your always maintaining a healthy earth via the negative battery terminal and meter probe.
you'll then find what you fried.

Possibly the alternator?

Sorry -should have been more assertive - PROBABLY the alternator. If they r the same as when I used to tinker, they have a diode pack which dunt like reverse polarity but is way cheaper to replace than the whole thing.......
