Did a continuity test between black and ground-no continuity with any ac switch position. Does leading a path to grd turn this system on? I would like to try and get a wiring diagram as I think it may modified. At some point it looks like the green pwr wire and black were wired together with a diode - does that make any sense?
The black wire should have ground at all times. Here is wire diagram to help with testing, let me know how it goes or if you run into more questions. Thanks.
Kind of wondered what happened to your reply and now I see you replied days ago. Sometimes just answer doesn't notify me of a reply for some reason. Thanks for that. I will have a look and get back to you if need be otherwise I will close the file.
