I took the alternator off my 96 Disco recently, but having forgotten to disconnect the battery there was a spark as the permanent live connection touched the engine whilst manoeuvering it out. I subsequently disconnected the battery. After all was finished I noticed that my radio wasn't working & displaying 981. None of the buttons would work, and no option to put in the code. I can get the radio to work if I turn it off & on again whilst pressing any button, but it makes a regular beeping noise & goes off after several minutes showing "security" on the display - & none of the buttons does anything. Any ideas please?
Cheers, Tony
