Reg97 Posted April 16, 2020 Share Posted April 16, 2020 Hi guys, installed a new head unit a couple of weeks ago now, over the past couple of days ive found it’s draining battery (had the car sitting for a day, whereas usually I drive it every single morning) used a multimeter and unplugged fuses and it’s the radio! however, this is as far as my limited knowledge takes me... it’s a Sony XAV1000 headunit. I followed the guide (I think correctly?) all was working fine, the head unit was turning off with the car. Is it possible that the amp is staying on? any guidance would be great (nearest electrical garage to me is a bit of an overcharging con artist) Quote Link to comment Share on other sites More sharing options...
mr v6 Posted April 16, 2020 Share Posted April 16, 2020 Only time I've ever had a head unit drain a battery (when everything was turned off) & it turned out the unit was faulty. Don't assume just because it's new it's ok, you never know. Quote Link to comment Share on other sites More sharing options...
Ben–350Z Posted April 18, 2020 Share Posted April 18, 2020 If you unplug just the head unit - leave all your wiring in place - does it still drain? If yes, then it's likely something wrong with the wiring, if no @mr v6 could well be right Quote Link to comment Share on other sites More sharing options...
