Surge turned out to just be a vacuum leak. Bruce - I already built a new cable. So that option seems unlikely.
Ray - Unfortunately I lost my Link interface box years ago. Bill - Last fall I was talking with Kieth and he had me do as you instruct. It rebooted. I was hoping the surge and reboots occurring at the same time would have help me isolate the problem, but that isn't the case. We are getting rain for the next few days so I will look at the wiring again next chance I get.
