No power to cab???

[MagnumForce]

Recently after a day of driving i pulled into a parking lot and shut the car off and when i came back out the car was getting no power to the ignition, the interior light wouldnt turn on and the rpm gauge didnt work. Nothing on the inside of the car was getting any power, but my battery was fine because my electric fuel pump, which is wired directly to the battery, worked fine. Then I jiggled the key and then all of a sudden it started right up and i got it home fine. Once i got the car home and shut it off, the same thing happened. My uncle got the car to start by bypassing the anmeter but still nothing in the cab works. Any advice would be appreciated

get test light out , i once had a bad battery feed lead to starter relay , test youve got power at all points , when it does it again, test those same points , it will show up , betting bad starter relay or battery lead

If jiggling the key made it work again, then likely the ignition switch is on its last leg.  Does the key feel loose at all?  If so replace the switch, if not then check the wiring on the back of it. 

Besides starter relay itself, check the yellow wire going from the relay to the bulkhead connector as well.

If all that and what fy mentioned checks out let us know.

If this search fails , I would look at the main culprit bulk head and plugs ,
Any corrosion seen here could be the cause, increased resistance on bad connections will heat up and fail , worst case will show signs of overheating and melt plastic

Got the same issue, replaced the red wire going from the starter relay to the back of ignition key switch, car fires right up and runs great but still no lights
