Isata 3 RW ground wire/ LED dimmer switch

[Kimjim]

We bought some ATC 12 V led dimmer switches as the LEDs are so bright. Spoke to ATC and they say we need to find a ground for the switches. We did find one (white wire) over the dinette switch. I have call Dynamax and the electrical engineer is hopefully going to send a wiring diagram. In the bedroom and kitchen, there is a slide out control near the light switch that has to have a ground wire. Hopefully, we'll soon find out which is the ground and tie into the slide control ground. Last switch without a ground will be bathroom. Don't know if we'll find an easily accessible ground in there or not. It would be nice if Dynamax had ground wires at all of there light switches.

All of our switches on the 2020.5 are multiplex and dimmable, so we bypassed the need for a ground, by just making them dimmable form the start. I guess that progress.

In the 2017 Isata 3 RW, does the wall between the bedroom and bathroom have aluminum studs?

Is there a ground wire that goes to the slideout wall switches?

I have already posted this question to Dynamax service department and awaiting reply. Will post when I get it. I did get this initial reply from Dynamax r/t wanting to install led dimmers and ground wires.

"So after talking with the engineer he said it will be very tricky to put dimmers in There is a ground bar under the sink in the kitchen, he thought you could pop the drawer out and the false panel and also the bottom base under the refer and possibly feed it. If you look under the sink and remove the floor panel you should see that ground bar and be able to trace and tie into it. There aren't any diagrams as those are free strung wires."

No ground wire to the 12V switches.No aluminum studs, they are wood.

If we purchased those switches would they work for the 2017 Isata 3? What switches are you using now?

They would not...its a completely different wiring system. I seem to think someone on here posted 12V dimmers, I don't think they needed a ground...or if they did, they likely just ran something to the frame. I never heard of an issue.

Something like this looks like it has multiple ways to wire it up.

NOTE: I am not endorsing this. Just saying, others were able to add a dimmer with very little fuss.

I put a dimmer switch in for the 2 lights over the bed. There were 3 or 4 ground wires together in a wire nut behind those switches. I have the FW, so may be different.
