Old thread but wanted to post an update. It's been over a year now and Ford never stepped up to replace this absolutely horrible inverter... probably because most of them are bad (I tested 3 different ones and all had the same broken waveform). I've never been a big fan of little battery power...

And the sage continues... I was hoping that maybe I had just received a bad inverter and since Ford was refusing to replace it (under new truck warranty or extended warranty), I bit the bullet and purchased a new inverter on my buck. Just installed it and exact same results. Messed up...

First Ford... didn't know that. Still suspect ours was dropped, kicked and thrown against a wall.

So pulled the cover on the inverter just to get a part number. Figured if it was cheap enough, I'd just replace it myself. I put the part number in on Ford's parts site and it comes back as "Low air pressure sender cover" for $1036. Can these guys do anything right? That price, by the way...

My understanding is the the only issues are with the 2KW package.

Side note on this, if I can't get the state lemon law enacted on this (or other legal means), I'll look into replacing the inverter with a 3rd party product. What's the best way to get wiring diagrams for Ford vehicles? Hopefully shouldn't be too hard to figure out without them but would...

Agree. It's even more frustrating when you ask them to look at it and they have no test tools... no o'scope and not even a multimeter. Simply plug in a saw and, if it turns, it's good.

So started a new thread on this because I made a quick summary video, still no help from Ford and the other thread had a lot of "other" information in it. Please feel free to share or post this video anywhere you think it may be helpful.

Just to document, have received no response to the PM...

So nothing new in this post... just needed a quick vent. Prepping our little camper for a trip and having to pack a generator and additional fuel is particularly irritating. Again, this is THE reason we purchased this truck as opposed to a Jeep Gladiator. I'll also add the generator we're...

Absolutely... thanks.

We have a busy period over the next week or so but I may make a quick video. Agree that some more exposure would probably help.

Well, several more hours of my life wasted. Went back to Ford today and this time showed them pictures of the waveforms coming off this inverter. Then showed them the frequency is reading 189 Hz (as opposed to a normal 60 Hz). Service guy admitted this was definitive proof this inverter was...

Not fingers... just a single finger tip can prevent a 10 amp circular saw blade from moving. I wasn't even holding the teeth but just pressed up against the side of the blade (I wasn't quite stupid enough to try holding the teeth). lol. FYI, I did plug it into a standard house outlet after...

Based on their response to the pictures of the waveforms, they'll probably say the clock was viewed from a gravity well so it just appears to run faster. On second thought, if they can't identify a simple normal sine wave, I'm guessing Einstein's general relativity would be a bit much. Sarcasm...

Yeah, the frequency issues are totally expected. When the waveform does more direction changes than a normal 60 Hz sine wave, those are detected as a higher frequency. The output of my inverter typically reads 160 to 190 Hz. This is so ridiculous... lol.

Appreciate the info and response. The voltage value itself isn't really the problem (as far as high or low), it's how it's presented. When the waveform (voltage) changes direction when it isn't supposed to, it just causes all kinds of problems and destroys the torque/power. I would love to...

So.... wanted to post another update. After looking at the waveforms again and seeing how the thing wouldn't even budge the compressor on our little RV air conditioner, I assumed those little direction changes in the waveform wouldn't allow an AC motor to run or would, at a minimum...

Yes, sounds like exactly the same problem. We also looked at a new truck on the Ford lot and it appeared to have the same issue. It appears as though Ford has a large batch of these inverters with problems and is refusing to even acknowledge it. We're paying for a legal service and I think...

So, wanted to post an update since it's been almost 2 months. Ford sent the pictures of the waveforms to their "expert tech" who saw no problems with the most messed up sine wave I've ever seen (I spent most of my career in power generation and electrical/electronics). Yes, their expert has...
