what a great idea. I tore down the failed pump from my 2006 Chrysler 300c and the commutator wear was very asymmetric. This would have picked that up before it failed.
that AC coupled fuel pump waveform came out decent for such a small amount of fluctuation in voltage an option for those without current loop and current current clamp or a tech wanting a quick look, a shortcut
Thank you for your videos. If I was checking the health of a duty cycle controlled pump and went directly to pump itself with the amp clamp, I should be able to see the segments, correct? Also if the tank and pump were out of the vehicle and I supplied the pump power directly I should be able to see the segments and judge the health of the pump, again correct?
Which year and model are you referring to? Depends on how “modern” the subject vehicle is… It’s my understanding that modern duty cycle controlled fuel pumps are usually brushless. So they’re are no segments because they’re are no brushes. The coils are static (stator) and the field is electronically switched (rotated). The rotor that drives the pump may have permanent magnets inlaid. No physical contact is made, supposedly improving reliability and durability. The electronics tend to be the weak link in the system. You maybe still able to monitor current to each leg of the motor, if the control is remote from the pump and an interface harness permits clamp on probe access. Again I believe they are usually 3 phases. Essentially making the system a DC to AC hybrid of sorts. Does that answer your question? I have a couple of videos on the channel regarding brushless DC motor control. They might clarify system architecture for you. Be aware simpler PWM control systems do exist.

I'm changing tanks on a 2011 crown vic and do not know the condition of the pump in the new to me used tank or my old pump. I have run vic pumps on direct 12v to empty tanks, so hopefully I can get some idea of the condition of both pumps and only put the new tank in once.
Excellent video, great info. Thanks for taking the time to share. Cheers
Thx so much. 🍻

good demonstration and clear info.

Minimal gear approach. Difficult to contrive something a little different on the scope. Cheers Denis. Hope your enjoying your summer 🍻👍
Another excellent, informative and very well explained video…as always…thanks. 👍👍👍
I hope you and your family are well.
Take care and best wishes 👍👍👍.
Thx Steven. Hope you’re doing ok yourself. And enjoying a seaside summer. 🍻
@@TheGibby3340 Yes, ticking over ok, thanks…It is more like enduring a cold wet seaside summer 😳
Aye…See that on the news. Never mind. It’s still early July 🤞

Hey, I have a problem with P0607 only during rain or damp morning. it says Data Programming Error when I see it via SZViewer.
Any ideas what to look?
problem is, when it has P0607, it goes straight to limp mode. Quite dangerous.
