Question F250 with pro power onboard canít ever get it to power the trailer

It shows a fault if I plug in the trailer to the truck bed socket. It will not power it. What is going on? Anyone else figured out how to make it work? It is not like the 7.2KW on the F150. Should be a single circuit. Help.

What did Ford tell you when You called your dealer service center ?

Ford does not run a power wire from the charge circuit to the 7 pin plug on its trucks unless you add it.

I had all the factory towing options on my 2015, but it wont power the camper unless you run a wire to the pin from the battery.

I hope ford did this factory by now, but I doubt it.

Did you check your fuseblocks?

On my '07 and my '17 F150s with factory tow package, the charge pin on the 7-pin socket was wired from the factory. On the '07 it needed a fuse installed. On the '17 it doesn't turn on the charge pin until after the first application of the brakes on the start after the truck detects plugging in the trailer.

My F150 did not work either. Some seem to work and some don't. I have not really seen an answer as to why

As you can see it depends. But generally, not connected for charging.

Has anyone watched the commercials for pro power onboard. They even use an Airstream in some of them. What is the point of have a 2KW generator while pulling a travel trailer if you canít plug into it when you are boondocking? On the upside, I am taking it in for 3 days to the dealer who seem to know less than my dog about anything on this truck. They have to do a recall which involves taking the dash apart to fix some problem with the displays. I will bring it up, but I donít have a lot of expectation of them to have a clue.

So, keep throwing ideas please.

If your dealer cant figure out something simple like this I would go somewhere else.

So, a number of posts (mine included) were off topic... I had visited the thread before, then when I returned it just showed me the "new posts" which were about the 12-volt 7-pin connection from the truck to a trailer.

Regarding your problems with the ProPower system, try a little basic troubleshooting on your own.
  • Shut off all breakers in the Airstream including the main 30A
  • Plug in Airstream, observe condition of ProPower
  • Switch on main breaker (leave others off) check ProPower
  • Close breakers one at a time and check ProPower

You may find that one particular circuit has some characteristic that the ProPower protection circuits don't like. If closing the main breaker causes the fault, there may be something about how the shore-power cord is wired that trips the ProPower protection circuit.

One assumes you've plugged other known-good things into the ProPower outlet to make sure the system works in less-complex situations...

Yes, I have plugged in simple loads and it works. I will try your suggestions when I am back where I have the trailer stored. Thanks!

Are there any warning or error messages being displayed by the truck?
What exactly do they say?

Do you have an EMS system on the trailer?


My EMS will not connect my trailer to my truck because the neutral and ground are not bonded. My truck will not allow me to plug in a bonding plug and disconnects the power. To work, I disable the EMS, remove the bonding plug most generators need for the EMS, and then everything is happy.

I had problems with my 2022 FC 23CBB and out 2kW ProPower on our F-150. The truck had a ground fault every time I plugged it in. Others have had similar issues as well, both with the 2kW and the larger 7.2kW, though the later seems to have gotten some firmware upgrades that fixed some people's issues. That model is also much better documents in community forums.

For ours, troubleshooting led me to the converter being the issue. We could keep all the other circuits on, run the heat pump, run a space heater (just not plugging into the GFCI plugs on the trailer) and it would run fine. Flip everything else off and flip the converter on, ground fault. Eventually, due to a lithium charging issues, my dealer warrantied the converter and replaced it with Progressive Industries, and now it charges! Magic!

I've had other charging issues with it as well. A fast charging larger power station (Goal Zero Yeti Pro 4000) did not charge while others (Ecoflow Delta 2, Goal Zero Yeti 1500X with 600W charger) did. I also cannot plug my truck into the generator pass through (basically a generator 30amp on one side, 6 15 amp outlets on the other) without throwing a fault. It all seems hit and miss, unfortunately.

True

Good advise and true. I looked for that fuse on our 2019 never found it.
I think the OP is referring to the 7.5 KW on board unit not the trailer plug. I personally would never use abuse my truck to idle to charge a trailer.

I can't wait to get my Cybertruck. It's got a standard 240 volt socket in the bed, that I can plug in while boon docking.
