Radio was working great today, then bam it quit. Checked the fuse found it blew(10amp) replaced it. Tried to power up the radio NOTHING... Checked ground wiring,it's fine, checked two other fuses fine....
If you already have your dash apart, have you looked for a fuse directly on the radio itself? There should be one somewhere near the power wiring on the back of it. If this is blown, you will be getting power to the wiring, but not to the radio. Replacing this fuse should help you out.
If this is not the problem, use a voltmeter to check the wiring where it goes into your stereo. If there is no power here, then the power overload that blew your 10amp fuse is probably related to a short circuit somewhere in the wiring between the fuse and the stereo. To repair this, you will likely have to run a few new power wires (you should replace both the positive and negative to make sure you have fully bypassed the problem) from the fuse to the stereo. If you have checked these wires with a voltmeter and they have power at the back of the stereo, but the stereo itself is not still not working, then the problem is with the stereo itself.
If you find that the wiring to the stereo all has power ... the fuses are all good (which you have already stated) ... the fuse on the stereo itself is in good shape ... then there might be a short within the workings of the stereo itself. If you are not experienced with repairing electronics this could be out of your ability to fix -- you can bring it to a shop or buy a replacement. If you are experienced with repairing electronics, open up the stereo and start checking the wiring (starting from the closest point to the power input and moving towards the stereo's face. This could be a long and arduous process ... so if you are not experienced with it ... I recommend taking it to a professional or just replacing it (your hair is probably worth more than the $100 you would spend on a decent replacement stereo ... and if you are like me, you would be ripping out your hair after checking the first few hundred possible connections within the stereo itself).
Hopefully it is just the fuse on the back of the stereo itself, and you can have that fixed in short order. Good luck!
