helloI was installing a GPS tracker in ford Mondeo so i needed 12+ volt from the car. and I take one from driver side under the plastic that' need to the driver knee. there I found many wires and I found red wire I took the 12v+ from it. but by mistaken that wire touched the car ground and now there's no electricity on it I've checked all fuses under the glove box and all fuses near to the engine and non of them was burned out please what should i do
There must be a blown fuse. The purpose of a fuse is to break the connection if the circuit becomes overloaded, this prevents electrical fires, and other dangerous situations. Blown fuses are not obvious if you just glance at the fuse box, you need to remove them in order to see the conductor. I would look at a wiring diagram, find the components on the diagram that are not working, and trace them back to the fuse number and location. This problem can only be a blown fuse or fuseable link.
