I need help 1987 B2 dead in the water.

My B2 has no power I turn the key over and nothing no fuel pumps coming on no dash lights no headlights no horn nothing comes on. My battery is good 12.68 amps. It started fine today I pulled up under a tree and cleaned my inside windows with mixture of vinegar and water and a squidge, I'm positive I didn't get anything electrical wet. After I cleaned my windows tried to start my engine and heard a pop or thump noise. Is it my solenoid? I hope its not that cpu brain box that would suck.

I found the problem the positive battery post was lose, I put new battery post on two weeks ago tightened them real good but I guess they got lose. With key on I wiggled the positive battery post and heard clicking noise I knew that was the problem. Everyone make shure your battery post are tight. Make shore the two nuts holding the red cable and the black cable are tight.
