I've been using a shunt for battery draw testing for 25 yrs. This way the ignition key can be cycled, doors opened, accessories cycled and won't pop an expensive meter fuse. Kent Moore still sells the shunt, just have to add alligator clamps. I don't trust inductive clamps for low current testing, and most of time it is difficult to get the clamp around all of the cables.
@@djosbun hey body he didn’t post it on his channel did he ? Last thing I heard was he have a training on Albuquerque where he lives however I didn’t go no money for me 😂
I haven’t met PJ but we have lots of friends in common. I’m going to Bernie’s class in Albuquerque in a couple weeks. He’s putting on a 4 day electronics class.
I made the same box after I was PJ made it. Works really well. Will look into the mill ohm meter. Would like to try it on some hybrid transmissions in the shop
I have to make one for my pico now! I learned soldering in the 70’s by building a Heathkit automotive big box scope, which still works. I can’t seem to part with it…. Looks like you’re getting more work out of the 3D printer!
I don’t get that magazine. I used to years ago. I ran across this tool in a class earlier this year and the training is friends with PJ so he referenced his video.
What brand is ur 3d printer, if I asked already sry, I have a question, on snap on, hooking up scope leads, yellow cable it can or can't be duel purpose, meaning yellow to yellow port, black im assuming to grnd port, can u use single cable without shielding, and the a separate cable to grnd port, sry new to scopes
My 3d printer is the Bambu XC1. I’m not sure what you’re asking about the scope. If you have a SnapOn scope use the leads that came with it and match the color lead to the port in the scope and black to ground. Stack the grounds if it’s a multi channel scope.
@fixingcarswith15thstautomo36 can u show hooking up ur leads in more detail, like when testing a two wire abs sensor, it has 12v supply and then sig rtrn i don't c pattern, thought I shld be on dc volts
The scope channel can only read the voltage drop across the resistor. That doesn’t tell us what we want. The math channel uses the voltage drop and calculates the fixed resistance of the shunt and gives us the amperage. It’s a calculation of Ohms Law. You can google ohms law for the relationship of resistance to volts and amperage. I learned it through automotive electronic classes. But there are lots of sources on RUclips to learn basic electronics.
Unfortunately once the video is uploaded I don’t have control of how it is received. The video I uploaded had no sound problems. If you have question during the missing audio ask in new comment and I’ll answer it. Don’t add to this thread because I may not see it.

Pomona makes great stuff. PJ is a good guy, excellent technician. Bernie Thompson made a shunt recently, too……definitely a great tool to have.

Get the Hioki meter. It’s expensive but the cheaper ones are not accurate. I got mine at aeswave.
Lost audio at 20:15-22:35 for me
same
I'm not sure what happened there, it might be a RUclips thing because the audio is fine on the video that I submitted.
@@fixingcarswith15thstautomo36 Please state how to get the resistor (what's it called...?)
I just bought a 100 watt .1ohm resistor from amazon.
@@fixingcarswith15thstautomo36 Thanks for the reply, so that's what you show in the video?

Import service magazine had an article on how to do that too.

Put your pos lead on the signal return wire and ground the black lead.
No sound.
I just checked the video and the sound works on mine.
@@fixingcarswith15thstautomo36 sounds stops for me at 20:10
Lost almost 3 minutes of sound
like right at the most important part
It was a good video until 20:10 when you lost sound.
Hi .
Good video .
Please help me …
What and why you need math channel ?
What is that for?
I just trying to learn .
Thank you sir .

I apréciate your time sir to answer my questions.
Thank you very much sir.@@fixingcarswith15thstautomo36
O men it sucks when the Audi when off it was getting interesting
I think that was a RUclips thing. The video I uploaded was fine.
I found that sound file and have posted a clip as another video.
Oh brother fix the audio please or fix the video or make another cuz when it really starts getting interesting there was not audiooo
