Power outlet blinking yellow

I picked up a used 2017 F350 KR and the power outlet light is steady orange for about 10 minutes then starts to blink. The rear outlet does the same. This is while I'm driving. I'm only using a phone charger in there. It's the same charger I used in my last 17 F350 which worked the entire 4 years I owned it.
Is there any way to check the inverter, or do a reset or should I just replace the inverter under the back seat.
I have searched but only get results on what batteries the inverter will/won't charge but not much on the blinking yellow light.

Thanks

From the 2017 Owner's Manual

When the indicator light on the power point is:
• On: The power point is working, the ignition is on and a device is plugged in.
• Off: The power point is off, the ignition is off or no device is plugged in.
• Flashing: The power point is in fault mode.

The power outlet temporarily turns off power when in fault mode if the device exceeds the 400 watt limit. Unplug your device and switch the ignition off. Switch the ignition back on, but do not plug your device back in. Let the system cool off and switch the ignition off to reset the fault mode. Switch the ignition back on and make sure the indicator light remains on.

You can use the 400 watt power outlet for these types of electric devices:
• Electric hand drills.
• Rechargeable power tools.
• Video games.
• Laptops.
• Televisions.
Do not use the power point for certain electric devices, including:
• Cathode-ray, tube-type televisions.
• Motor loads, such as vacuum cleaners, electric saws and other electric power tools or compressor-driven refrigerators.
• Measuring devices, which process precise data, such as medical equipment or measuring equipment.
• Other appliances requiring an extremely stable power supply such as microcomputer-controlled electric blankets or touch-sensor lamps.

I'm assuming the inverter is bad. I might be pulling 10-15 watts with that phone charger. But not 400. And like I mentioned it is the same one I used for 4 years with my old truck.
I wish there was an option to upgrade to a pure sine wave inverter.

That has been mentioned quite a few times on the forum. A PSW inverter with a higher watt rating would be nice. If someone produced a plug-and-play replacement I think it would sell.

I put a 1100w in mine were the factory one was and ran new wire to the outlets. Ran a wire from the upfiters to trigger it on.

ETA: that’s a lie, I put it on the back wall, not we’re the factory one was. I need a better pic but you can see it here under the amp for the sub.

Nice. But do you have the 360 cameras? I read somewhere on here that the 360 cameras needed the inverter to operate. If you do have them, do they still work?

Lol, nothing related between the inverter and 360 cameras. I have both.

I just unplugged the inverter and tucked away the cables, no codes or issues.

I thought that sounded a little strange, but nonetheless it was written here.

I'm assuming you ran ALL new dc wire from the batter and AC wires to the outlets?

Yes. One 12v DC from upfiter to trigger the inverter to turn on(get a inverter with a rocker switch and then just tap it into these wires). Then new AC wires from from the inverter to the outlets.

If you click on my threads and look at my build thread there is some info in there but I need to update it.

I have no idea how they tested the factory inverter and came up with 400w, won’t run my laptop either and it’s not even 300w.

I ended up removing it and replaced it with a 2000w inverter, replaced all the wiring to the outlets with larger wire to handle it.

Wasn’t a easy job as the dash and console had to be removed but it was worth it to me as I use my truck as a mobile office.

Now I can’t run all at the same time:
Laptop
Printer
Boot Dryer
Phone Chargers
Heated pouch for heating lunches.
Etc

It’s not that I can’t handle the power, is that the inverter is providing the wrong type of power for your laptop. Your laptop, and then the other lithium ion battery devices like drills, etc. use chargers that require a pure sine wave before hundred watt rating is accurate but Ford fell short with the cheaper, dirty wave inverters.

It powered my old laptop just fine with a lithium ion battery
