lost power

[dlp750]

I have lost power to the dash gauges,power windows,door locks mirrors,sunroof.Car starts and runs fine.I pulled the tach out to check the ground.ground is good but no power at the ign sw terminal.Could this be a bad ignition switch? worked fine one day next day nothing.This is on 84 touring Coupe RQB3866 thanks

Checked the ignition switch today looks to be working right.Anybody have any ideas?

By "working right", do you mean that there is power to the switch and power out when the switch is on? This would be counter to your previous statement of "...no power at the ign sw terminal."

Are you sure that all of your fuses and circuit breakers are okay? At first, I thought that you (your Avanti) simply blew a fuse.
