blue crush Posted May 3, 2015 Share Posted May 3, 2015 Fitted two sunvisor 7inch screens to my focus, linked up to a switch which is powered from perm live off cig lighter. Also i have my mobious dashcam linked up to same switch so that i can switch all off while not using. On other side, i have another switch for my rear cam as i hooked it up to same perm live too so that it is on for towing purposes. But can be switched off when not using. Havent used my car for a few days and battery was dead! Could there be a slow power draw from all the stuff i have off the perm live? Should i hook up to ignition live instead to solve this problem? Hope all makes sense and someone can help with electrical solutions. Quote Link to comment Share on other sites More sharing options...
GingerFlame Posted May 3, 2015 Share Posted May 3, 2015 Run a permentant live to a relay controlled by the igntion switched live. That way you don't draw too much current away from the switched live :) Quote Link to comment Share on other sites More sharing options...
jeebowhite Posted May 8, 2015 Share Posted May 8, 2015 Agree with GingerFlame, the fact your running so many permalives is likely to be the reason. I have nothing on permalive at the moment, all my gadgets are powered off 12v USB which is an ignition live only, and I havent had any issues, however, in the older days where I ran everything off the focus perma live 12v, I did get close to flattening the battery a few times!

blue crush Posted May 8, 2015 Author Share Posted May 8, 2015 Cheers guys. Can you show me what you mean with relay etc for the ignition live? I assume hooking a wire onto ignition of radio? Sent from my iPhone using Ford OC Quote Link to comment Share on other sites More sharing options...
GingerFlame Posted May 8, 2015 Share Posted May 8, 2015 Run a wire from the battery to the relay, from the relay to your devices. Then run the 12v ignition switched as a signal for the relay Quote Link to comment Share on other sites More sharing options...
jeebowhite Posted May 8, 2015 Share Posted May 8, 2015 I ran a wire from a spare 12v fuse in the fuse box to the relay 12v input. I then ran the outgoing wire to my parking sensors, camera and reversing screen. It's always disconnected but I ran a wire from the reverse light to the switch on the relay. So when power goes to the reverse lights, this powers the switch on the relay and takes a direct feed from the battery to power my other devices. When I stop reversing and take it out of gear, the switch opens, the power flow stops and everything is off. Quote Link to comment Share on other sites More sharing options...
