I have 2002 ford focus and I installed a new stereo system it was working fine.... then I had to pull the stereo out again b/c I forgot to install Mic. and cig lighter.... after I hooked those things up I went to push the unit back in...... and the stereo went dead......
At first, I thought it was a fuse or relay
so I check fuse box under the steering wheel..... Nothing Blown
check the fuse box under the hood...... Nothing Blown
So that was all good
SO FUSES AND RELAYS ARE GOOD.........
Is there a third fuse box under dash????
The New stereo unit has two wire harness inputs
One for speakers and audio
Second one is for POWER (((( PROBLEM))))))
(Consist of )
*12V BATTERY WIRE
*12V IGNITION WIRE
((((I tested this one with a volt meter and it was dead even when key turned)))))
I crossed the *12V IGNITION WIRE & *12V BATTERY WIRE
The Stereo Unit powered on....
Something is causing my 12V ignition wire for the stereo not to function
