Hi guys. I have a 19 plate and its just developed an electrical issue. When I turn it off, the electrics all suddenly kick in - the lights flicker, the dash stays on and the fan runs. I have to disconnect the battery to power off. The fan running tells me its not just a case of it wont switch off, the fan doesnt come on with the ignition unless its hot. Has anybody had a similar issue? Any ideas what the problem could be? Any advice would be hugely appreciated!
