Car Stereo Won't Turn On?

[chrispb123456]

Yes the original stereo was affected in the same way, doesn't look like anything else has been wired into it?

If I was you I would start by removing the wire from terminal 8 on the ignition switch, with switch off test for voltage on switch terminal 8 if it's dead then switch is ok.

If the removed wire is live then currant is flowing back from instrument cluster or central junction box.

Really strange, my wife used the car today, and she fiddled with the stereo and now it's all working fine??

Cheers for all your help.
