Why do I not have power?

Also check your grounds. A bad ground can cause this. Afaulty ignition switch could do the samething. Remove the dash section beneath the steering column. Once removed you should see the nuts you need to remove so column can drop. You should see the ignition switch. With the key in the off position use a test light and check for power at the switch. If you have power going into the switch.then turn the key in the on position and recheck if you have power coming back out from different wires. BTW There might be a few sending power out. If nothing changes then I would replace switch. It's been awhile since I worked on a bronco. So here goes; the wires are red,redw/orange stripe and maybe purple but don't quoat me on that. Make sure and check all your grounds.

I must have a linkable fuse bad
