Roof plug issues

[MNV]

Has anyone had issues with there being no power to the roof plugs (ext2/3) switches?
There’s nothing there with appropriate switches on and lights plugged or via a multimeter.

Thanks In anticipation!

The front left plug was inoperable with my car. There is another plug in the interior behind the roof liner which they forgot to connect at the factory, so no current at the roof plug.

The Bosch Service cured it but they told me how difficult it was to solve this issue. They had to talk to Ineos engineers twice before they found the interior plug.

Without having accessories with which to test them, what's the best way to check?

Switch the roof plugs (ext2/3) on. Connect anything electrical (light) with a Deutsch DTP plug to the roof outlets. Or use a multimeter.

Looks like one more tool to put in the bag before I fly up to Colorado Springs Friday to pick up the Grenadier. Maybe I ended up make some test leads with Deutsch DTP plug at some point.

It should be noted that the OP most likely has a MY23 vehicle (as does WhiteBear ), so these are less likely to be found on the MY24s

I added to the list of things to check, it 311 miles ( 500 Km) to the dealer once I am back home.

Yep FY23 as suggested.

If people what to use a circuit test light, use the LED version, no feedbacks like you can have using the older style circuit test lights. Downside is that LED circuits testers cost more.

I instantly get 12v, for a microsecond on the multimeter and then nothing. It's very odd. Is there some sort of diode or resistor in between the switch and the socket?

Anyone figure anything out with this? I’ve got a MY24 model quartermaster not long ago (older model but brand new). No power for ext 2 or 3. No power to the fuses but all 25amp accessory fuses have continuity.

stupid question:
Does the problem exist when the ignition/ the motor is on? Did you switched on the pwr switch when trying ext 2 and 3 without ignition?
I know that you probably did this. But if not it could be the fault of.

Yeah checked with both the auxiliary power switch on & engine off as well as engine on/

Agree
...the LED version is the safe way to go.
For a simple DIY project:

I put one of these together in about an hour (including coffee and cake time) one wet Sat afternoon.
The cost was just a few dollars after rummaging through the parts bins at Jaycar....
