Fitting My Headunit Problems

[Lee Bali]

i just tried to fit my headunit into my car all was going well. i tested it then screwed the dash all in place agin and it just wouldnt work. took the dash off one more time tested it but it kept going on and off like there was a dodgy connection. tried all wires they seemed fine. at this point i managed to get the headunit to stay on constantly so screwed the dash back on. now ehn i switch on the power to the car the hedunit doesnt work, neither does my old radio come on at all and the cig lighter socket doesn work either.... any suggestions !!?? im screwed

You tightened up the Battery terminals tight again?

no head unit was working completely fine but as soon as i screwed the rest of the dash on or pushed the headunit all the way into the dash to screw in the bottom part of the dash it would just turn off. and not turn back on

have you checked there aint no wirin chafed also try unscrewing the screw out of the side of the unit i did a yaris the other day with a sony in and when i put the securing screws through the side it was cutting the amp for some reason and wouldn't work try that it could be touching the ip curcuit in the stereo and shortin it out. it was the back right screw on the sony

i dunno i used really short screws something like 8mm eactly which came with the headunit.

i still have no idea what it could be but my fiorst thing would be to change the fuse (if it has blown) but working out why the headunit randomly looses all power when u push it into the dashboard is another story

have you used an iso plug or have you chopped the wiring if you used iso where did you get it from the only other thing you can praps do is put a multimetre on it and see what you are loosing if it earth or lives remember you have perment live an ignition liveand then earth you need to find out what is going?

[Lee Bali]

yeh i used an ISO lead from a site on the net... they're very reliable though

check that the pins have not pushed out the top did it go straight in or was it a struggle to get it in

check to make sure you didn't bend one of the pins, it can easily be done without realising it.
