radio fuse? possibly!

[rousetafarian]

hi there,

first post on here!

I recently took old original stereo out of the car, cut wires and re wired them, got it all working fine... but then as i was faffing around i knocked a earth with a ignition wire on back of stereo and now have no power coming through wires.
fuses in the engine bay fuse box seem fine!
so why no power?
any help much appreciated.
also what do people use to wire from battery so that radio stores stations?

cheers!

all wire are there! all you need is a meter and even ones from the £1 will work fine. if your system is not holding its memory and you have wired up all 3 main wires (red , yellow , black) swap the red and yellow around its common issuse on sum systems , and check the fuse on back of the headunit.
