Again, there's some misunderstanding here. The "cable lug" that was installed here is not the bolt everyone is talking about. Every Maverick comes with that bolt and a factory cable lug for the positive terminal. The soldered connection that is failing is where the harness is connected to the factory cable lug. In this instance, they peeled back the "tape", saw the faulty solder, threw out the old cable lug, installed a new one, and resoldered the harness. The bolt everyone claims is the new fix literally just attaches the cable lug to the terminal. New or old.
Right, I haven't seen where anyone thought it was the actual bolt.

Thats the 12v distribution block. All that is 12v HOT, be careful.

Did you really tug on the cable while watching the DVM?, it has to be done at the same time. I would move it side to side, push on it while watching meter.

If you want it to fail, give it a good tug and i bet the cable will dislodge from the lug.

There are several who have been misled to believe that the bolt was Ford's fix on later models. That those with the problem do not have this bolt, and that it's all that is required to fix the issue 🤦‍♂️

Yea did that both stayed at 3v on the multimeter while wiggling both side to side. I think the cable solder points are good. Not sure what wrong with mine

thanks for sharing your story.. may i ask how you did most of the jumpstarts ? Did you jump started from underneath the rear seat or at the designated pole under the hood? My understanding was that the car could still be running aslong you don't turn of the vehicle..

and what if you were 1000 miles away from home? can the vehicle drop dead just like that at 65mph or at the traffic light / at the gas station? Lol

worst thing would be to stall dead on a bridge or in a tunnel

i have a small battery jumpstart and s couple of clamps.. but i suppose you didn't try to clamp the joint when that happened..

anyway, let me know how you jumpstarted it? Cuz i have tons of stuff on the rear seats that i have to remove to access the battery underneath in case that happen
We jump started it under the hood. It fired right up but it did keep dying, even at 55 mph just going down the road, everything just shut off. We were just under 100 miles from home. In total it took 4 hours to get it home with all the starting and stopping.

Rj, thx for diagnose, we may be on to something else. A couple of other members were suggesting that the problem could be elsewhere. Some offered up that it may be another point along the cable.

Please offer up and post what the dealer finds, your data could be the piece that solves the puzzle, it would be real nice if you could see the cable and tell us what the material is?

Others are saying to file with NTSB?

Thx very much for letting us follow you on this rough journey with the Mav.

Found on FB. Recently repaired dead hybrid. Many threads on this issue so I posted it in a couple.

Its so common now they have it named acronym BCE, if this is acceptable repair to there defective connections, i will do my own repair.

Like other people have brought up, if 1 connection is defective why wouldnt the ones be defective?

That may be the exact reason Ford is replacing the harness as opposed to the termination.

Send that picture to Ford...
Very cheap and Dangerous way to make a main supply cable. Who is leading Ford's supplies, Ford or crooked supplier?

Sorry if i offended you or anyone else but at the end of the day I stand firm in my personal opinion. Theirs been fairly large numbers of reports of glowing red catalytic converters, dead batteries, bad wiring harness, going dead in the middle of the road since deliveries started being made. Ford has put the burden on their customers to put battery chargers on brand new vehicles-to me thats unnacceptable. It's getting fairly close to the next model year order banks to open, Ford has known there is an issue with the hybrid version, particularly with battery and wiring harness, but unless I'm mistaken, ford has yet to issue a tsb or recall. What does it take, someone getting killed in the middle of the road because their brand new vehicle went dead in the middle of highway traffic. In my opinion, ford has dragged their feet in a prompt fix. These type things should have been caught in vehicle mule testing and decent quality control at the factory, along with quality control by the mfg of the components. No one should be astonished that a consumer should expect a brand new vehicle to be reliable and not leave them stranded - that is sad day in my opinion that consumers have lowered their expectations to be ok with substandard quality control and reliably in a brand new vehicle. If it was a made in china POS it would be a different story, but we're talking Ford, a USA Manufacturer that has been producing vehicles a very very long time. Where has the pride and standard of Qualiity gone? Yes I'm sure their will be some to disagree with me, and some that will agree with me. This is my opinion and everyone has a right to have theirs.
Quality # One!?

From Space/Aviation 6 reasons for Harness Failure


Let’s explore how wiring harnesses are made, and where companies can run into issues during the initial manufacturing process. Ensuring that you start with correct materials, wires, connectors and configurations will go a long way to guaranteeing the quality of the end product and that it doesn’t prematurely fail after installation.

1. Incorrect Wire Preparation and Staging

Preparing wires for a harness involves: selecting the right wiring product, cutting it to the specified length, and stripping the ends. While this is often done via an automated machine, user error and poor machine maintenance and adjustment can lead to problems. Make sure you are selecting the right size wire, and that the machine is adjusted properly.

2. Poor Wire Harness Layout

Beyond prepping wires, if they are not laid out correctly to be connected to the harness chassis it may not fit in the finished product, or may lead to excessive lengths of wire that will need to be trimmed. Often, creating a form board can help technicians easily identify the wires needed, if any are missing, and where they should be placed.

3. Shoddy Labeling

Probably one of the most common problems experienced with mass produced wire harnesses is improper labeling. One good way to make sure the wire harnesses you receive are labeled correctly is to develop a system that checks for accuracy before the labels are even printed. One good way is to create sample labels for your mock-up or traveler product when you place the work order.

4. Defects in the Crimping Process

Crimping is by far the most widely used method for terminating wire ends. When crimps are not done properly it can lead to short circuits or open circuits within the product. Or, the crimp could spontaneously fail, even if it passed a functional test. Regardless of whether you are hand crimping or using a machine, it is important to ensure equipment is set up correctly for the size of wire you are crimping.

5. Defects in Soldering

There are many issues that can arise when soldering your wires to their terminals. A soldering temperature that is too cold or too hot, poor soldering technique, or using the wrong size of iron tip on the soldering gun can all lead to issues within the circuit, and eventually, the finished product.

6. Wrong or Missing Hardware

As your line works quickly, constantly trying to meet deadlines for production, it can be easy to overlook a wire with a missing terminal connector, or that the incorrect wire is attached to the wrong hardware. Often, the best way around this is to train technicians to double check their work against the assembly specification documents.
