    This is semi related to this thread, and I am not trying to hijack it. But I thought I'd go ahead and throw my question in to the mix if that is ok. I have a 1980 Z with delay wipers. I thought the wiper motor was bad but before I changed it I wanted to make sure. I started poking around with a test light to make sure it was getting power. It was, but when I put the test lamp probe into the green terminal on the motor, it started working. It's not lighting up the test lamp, so I know it's not a power wire. A test lamp isn't designed to create a ground circuit, so I know it's not a ground wire. What could possibly make the wiper motor work just by sticking a test lamp probe into the green wire terminal? Any help will be greatly appreciated.
