In the area under the television there is a wall outlet "Charging Station" with four USB ports. I've tried all four ports and all four are dead. I have 12 volts coming to them, so that's good. I also got out my volt ohm meter and tried to determine continuity between the red and black pigtail wires and the contacts in the outlet - nothing. Patch cord works fine in the outlet on the dash.
I found on the back of the wall outlet the name "Sigma Elkhart Indiana". Checked their website and found the socket, part number 12VOTABUSB - here: https://www.sigmaswitches.com/PDFs/u...ng_centers.pdf
Anyone have any experience troubleshooting these?
