Hi,

Yes with it connected its over 4amps, without it 0.2-which i would imagine is the central locking and clock etc, so normal??. yes its the original headunit. the previous owner said that it had never been touched since he owned it. the wiring looked like the original and had ford sticker/tabs on still, nothing looked damged or corroded. I suppose the only way to tell would be to try another unit? might explain why in my first message when i turned the headlights off the sound stopped and when i turned them back on it started again. hasn't done it again since though.
