Hi my name is Robert....
Are you saying that nothing at all on the dash is working?
There has to be a breaker tripped somewhere, go to the battery and check your voltage, make sure all the cables are tight, check the ground going to the frame, if the battery was removed verify the cables. After that follow the cables from the battery to the fuse box, use a test light and probe for power, below is a style breaker they could be using that kind has a tiny tab that pops out on it when it trips.
I want to also say back in the day they could have used an ignition solenoid, follow the cables and see if they are going to a solenoid, if you find one check the large posts across the solenoid and see if you have power. IF you only have power on one side jump the posts and see if the power comes on, OR have the ignition key ON and have someone watch when you jump the post. Also sometimes they would use a plug connector, they would bundle a bunch of 12 volt wires and use plugs, sometimes they can vibrate loose or get corroded. I think your best bet is to start at the battery with a test light and trace the power to the fuse box, then inside..... Hope this helps some... Robert
