2018 Winnie Drop Slide out not working

[Sabre3]

Hello,
This is my first post and I come looking for some help.
I have a 2018 Winnebago Winnie drop. The slide out quit working and I can't seem to figure it out.
I discovered a chaffed wire where the wiring bundle goes through the floor, I replaced that wire from the control box to the auto-resetting fuse.
I replaced the auto resetting fuse on the inside of the left front frame rail.
There were no lights at all on the control box (Lippert #13398-DO)
So I bought a new control box and still no worky

Looking for some ideas?
The slide out makes no noise at all. No effort to operate

I would backprobe the harness connector at J2 and J3 on the black and red pins using my multimeter, if your probes are too big for that then use a pin to packprobe and hook your leads to the pins.

Yes, there is power coming into the control box. How would I check to see if power is coming out of the box?

Did you check for 12V input coming into the control box before replacing it?
