The outer pin cap is there to open the spring contacts and wipe them clean at insertion. Sometimes previous users of charging equipment are a bit careless with the charge cord and it gets foreign material in it. It's a area that one wants to keep as clean as is practical.
Remember it's controlled by what the camera ahead of the rear-view mirror sees. Mist, bird dung, bugs all effect it. Especially oil coating and wash wetting agents. I had pine sap interfere with mine once.
That's on the rental agent for not knowing his client and walking him through the operation of the car. And I've had contact with the same engineers for 45 years. Sub's are special, and their engineers are more so.
Exactly. Let's say that the low voltage charging is on a second after the main contactor opens. The current from the caps would cause a point arc. We don't have hard facts on what they found, but yes, timing is critical.
Timing does matter because they use a smaller contactor and resistor to charge the large capacitors in the motors. Without the resistor the capacitors are capable of drawing well over a 1000 amps. Once they are charged, then the main contactors close and the car is ready.
By using capacitors at...
Wire amp charts are specific to wire design. Like MTW is a lot more flexible than THN and has a higher amp rating per size. 4-0 welding wire is very flexible.
It seems that Ford periodically checks the car. Determines what you may need, and sends a update. Each vehicle is different because of so many variables. Dealer visits, build equipment versions, Trouble codes, and subscriptions/accessories. They are tailored for your car and it's needs. So don't...
Part of the code not only covers the circuit design, but all appliances that are UL approved in the US. They also have to have a overcurrent protection inside. Often a fuse or fusible link. Operating at lower than design is actually good for the longevity of the device. Less heat. All electronic...
