Having problems with your Cars & Trucks ?
I have a 89 ford mustang gt
I was installing an after market radio
And I accidentally touched the ground red wire and 12v yellow and black wire together now my ground wire is not giving out power. I've checked the driver fuse box and the fuse isn't blown for the radio and I also know the fuse is working because the truck release works and that shares the same fuse with the radio help please I'm tired ff driving with no radio.
You are confused. The ground wire never carries voltage. From your description it sounds like you have hooked up the radio incorrectly
