Main room slider working!
I had posted a couple of threads on troubleshooting a non operational slider in my 2005 Jayco Greyhawk. I was also correcting an issue with the battery disconnect and solenoid feature being disabled by a previous owner.
I found a slew of white ground wires underneath the house battery tray. At least 3 were broken. They screwed into a screw block plate that is bolted to the frame. The screws were rusted, so I was not able to reuse them. I tugged on the other 2 dozen white wires, and 3 more broke off. I ended up crimping good quality yellow eyelets (NAPA auto parts) onto the broken grounds, then drilling a few holes into the frame, then used good quality grade 8 bolts, nuts, and washers to attach the wires to the frame.
My main room slider now works! I suspect other electrical items I have not used in awhile will also work without a suprise when I need them.
Lesson learned for future troubleshooting grounds....check this area for loose or broken white wire grounds if you have issues with non functioning electrical things in your camper.
