today i fitted my aftermarket head unit in my new car, a ford focus. Its the same aftermarket head unit i used in my old car and i had no problems. After i fit it today it worked fine. About three hours later i went back out and the car started but choked a little bit. Another three hours later and ive gone out again to find that the electrics seem to have gone. The car wouldn't start electric stuff like the interior lights, stereo, dashoboard lights etc came on and went off and there was a faint thud sound and then everything went. There seems to be a little bit of life in it but theres definitely a problem with the electrics caused by the head unit fitting...
I'd be greatful for any help please!!!!
did you use a connector between the heaf unit and the ford wiring? sounds like the wiring is wrong causing battery drain like this
ive included the correct wiring im assuming youres is the same . the head unit you fitted did it switch on with the engine off and key out of the ignition? it shouldnt the focus has a switched feed so the headunit should only switch on with the ignition switched tio the acc position sounds to me like you have got those wires mixed up and youre providing it with constant power hence the battery drain. if youve cut the wires to fit then you need a multimeter or connect the original ford plugs back on and get a proper connector
