lose all electrical power when the key is turned to start
2012 Chevy Express 3500. 1st sign of problem was noticed when trailer lights did not work. A few minutes later I lost all electrical power with the key in the on position, but could hear a clicking noise from inside the fuse box under the hood. When I turned the key to the off position, clicking stopped. Now dash lights up when key is turned on, but lose all electrical power when key is turned to start.
