Same problem! 2 vehicles! Nothing happeneds when i turn the key! No lights, radio, fuel pump, or crank?

i drive a 1977 Dodge b200 and it broke down yesterday due to an unrelated issue with the fuel pump i installed through a toggle switch. When i went to try to get it running later that night i got absolutely nothing when i turned the key. No headlights, dashlights, dome lights or anything. Brand new batery and i did several drop tests across the batery, starter relay, and the starter. I also ran the starter strait to the batery to make sure the engine would crank.

Earlier that morning i was working on my 1983 Honda magna (the motorcycle) I have a brand new starter relay, and a batery but when i hopped on the bike to go for a ride nothing happened. Again, no headlights, dashlights, fuel pump, Connections are great, also did a test on the batery.

I'm out of ideas!
