Randy told me to check out my Cycle Inhibit Adapter harnesses, which was the problem. It has a short in the wires that are not wrapped. I am just going to replace the harness. But it was really weird that the changer had the same error yesterday 3 times in a row. Then today it worked for 10-12 bills until I touched the harness; then I could make it turn on and off by touching the wires. Great feature!
