I don't buy the all chrome causing the problem. If someone could explain the logic behind all chrome causing the problem, I'm listening.

This is a text book example of a high resistance, either at a connector or most likely at the point of ground. Try cleaning the jam switches. Use some electrical switch cleaner, depress the switch, and let the switch snap open. (Watch the switch cleaner around vinal.)
