2003 Astro Cargo with 160,000 miles. Was starting/running fine. I got in it, turned the key and nothing. No action from the gages. Dome light, radio and headlights did not dim when turned to the start position. Radio display got brighter when attempting to crank. I removed the battery and took it to O'Reilly for testing, they said it was fine.

I'm stumped on this one. Any ideas?
