Didn't understand a single word you said.
ОтветитьWow, you have over a million subscribers. I'm happy for this
ОтветитьNot a good video for the average person....much easier way to explain it
ОтветитьWhere is your automotive school at? I need to attend that.
ОтветитьAmps is the lazy one that doesn't go anywhere unless theres a clear path to ground
Voltage is the active one thats always on the go, until something get in its way or send it on a detour,
for example
A break in a wire is like a bridge that would've carried you on foot straight home had it not been blocked by cops all of a sudden , now you have to detour a much longer way which will then drain some energy from you by the time you reach the other side, that blockade can be one of 2 things, a switch that will drain a required amount of volts which is normal or resistance thats contributing to more than normal voltage drop, bad switch, break in the wire, rust corrosion etc
I’m dizzy
ОтветитьJibberish. You think you can measure voltage drop on an alternator circuit....with engine running???? Did u fall and bang your head ? Any alterantor puts out well over 14 volts...and its variable across all atllterantors. This whole video is rambling drivel.
ОтветитьLittle bit complicated as I have to start over again good job for helping some of us to a new level of knowledge. God bless yall
ОтветитьWow he helped me understand that super fast!!! Damn man your a good teacher 🤘🏽
ОтветитьGotta say this was very confusing. I think you failed to explain to someone who doesnt really know the basics. In your first example youre measuring the voltage drop clipping on the positive side coming into the needle part of the bulb tester and the ground on the battery. Then in your alternator example you talk about measuring first the positive side voltage drop then the negative side. I saw other videos so I get what youre doing but this one just felt like one of those videos where you skip details because you know what youre saying, but its a little too vauge for someone who doesnt know. But thats just me. The comments are divided between people who got it, people who were confused, and people asking for unrelated advice. Also examples are always helpful. Maybe wait till youre ready to provide an example of your concepts. Thanks for your videos though. They have been helpful.
ОтветитьExcellent video No hookers, but still really good.
ОтветитьWhoosh. Most went over my head. Electrical is definitely not my strong suit! 🤣 But you are a great teacher 👍
ОтветитьHi, I have. problem with dodge caravan. I changed the alternator and the battery was tested it is working, however. There is a sharp rapid drop in voltage after I turn the engine off. does within seconds from 12 to 9 volts. I have to jump start every single time I turn it off and even for gas filling at the pump. Do you have any suggestions on what that might be?
Ответить🤡👍🏼
ОтветитьSo, the test light was using 7.6 volts and fuel float was using 4.3 volts. That would be 11.9 volts total. Supplied voltage from the battery was 12.3 volts. This would tell us that 0.4 volts was being used from another source, which most likely was from the wires connected to the battery or the battery terminal connections. So, the complete circuit would have 0.4 volts of resistance?????
ОтветитьThank you man
Ответить"I dare you! Ask me more questions!" I thought that you did a good job explaining this concept in the context of working on a vehicle. I would like to see you do this to check the WIRES to the O2 sensors on a chevy Silverado, preverably as it applies to the 2000 models. (mine's a 1500 ;) )
ОтветитьI LOVE the new way he says, hey hey how is it going Do.. it your... sulfers.
ОтветитьThis was a great video explaining circuits, resistance, electrical theory. I've taught myself how to read wiring diagrams to to the level of adding heated seats and power windows in a manual window car. Everything worked 100%. A great sense of accomplishment for me. Toyota dealer was impressed because I designed circuits to bypass bcm with stand alone harnesses. Excellent content made perfect sense.🙏
ОтветитьLove it , are you located in Los Angeles
ОтветитьCan you help me I have a Mazda mpv and it will idle when I unplug mas but when I plug it back in van dies
ОтветитьI got lost when you tried to explain it maybe I’m not advanced.
ОтветитьWhat would you recommend (tune-up wise) on a car that's been inactive for 5+ yrs?
Thanks and love the content!
I’d like to say thank you for sharing your knowledge. Great topic . We are now hitting at the gold in the mine ! Let’s get some ! Keep it coming please !!
ОтветитьI miss you homie
ОтветитьA lot of vehicles use ground going to the ecm to send signal to the sensors can you explain more on those?
ОтветитьI don't think this was explained well. Made it too complicated. You're trying to work with a voltage divider circuit and using that to detect the state of the device that is dropping voltage (presumably for a position that correlates to a changing resistance level of a variable resistor). The end comment about 12 v. when unplugged is also confusing. There are voltage grounded circuits, where the 12 volts is being supplied by one wire, then going through the device, and then back out to a PCM with a circuit that has internal resistance, and possibly a transistor circuit for bias (switching), and is grounded. The resistance outside the PCM, along with the resistance inside the PCM provide a voltage divider circuit, and affect what is sensed inside the PCM for decision making elsewhere. The sidetrack onto voltage drop across fuses was also confusing. Basically too many concepts/examples across too little time while jumping around the engine bay also contributed to the confusion.
ОтветитьIn a series circuit the sum of all voltage drops is equal to source voltage. In series circuit the the current is the same throughout the circuit. In a parallel circuit voltage is the same but the current will be divided in each branch depending on the resistance. If all the branches have the same resistance then they would also have the same current.
ОтветитьKirchhoff’s voltage law baby!
ОтветитьWhen you do a formula and then simply wing it, without putting up any real numbers, you simply will lose an audience who is trying to grapple with the concept of electricity and that’s difficult enough. A formula without a number and example based on a real world demonstration, just causes people to shrug their shoulders and basically say “I don’t understand.“ And that was me who kind of dropped off about five minutes into this. Sadly.
ОтветитьOnly commenting for the algorithm
ОтветитьGreat tips thanks!
ОтветитьI'm a "long" time subscriber and I'm ok fixing my own car as long a lift is not required; however, this video is for way more advanced viewers. It's something I would love to understand plus I'm very excited you're back into car repairs. Admittedly I hope you future videos are not as complicated. Keep up the great work and I appreciate what I've learned. FYI I purchased a car (2008 Honda Civic) you recommended on you older videos for my step daughter. She still has it and it runs great.
ОтветитьYou were asked and you delivered!
ОтветитьGood video but I didn't understand sh***t. Electricity always been so complicated to understand.
Ответить"Hey hey hey do it yourselfers" reminds me of the scene in Scary Movie 2 when the disabled guy is being seduced by the big boobed brunette, and he says "hey hey hey I can do it myself" 🤣
ОтветитьThe alternator isn't going to try to charge the battery from that test wire, is it? Just wondering if it tries to send 10 amps through my multimeter?
ОтветитьI love the Ratchets and Wrenches channel, but I didn't seem to get much out of this video.
Ответить@R&W - Just two questions (1.) In most shop manuals, you'll read, in bold print -"Do Not Test Grounds Using Vehicle Ground" (or something to that effect); I guess there's fear of errant 12V running thru the ECU. Is this the case? (2.) And I've seen old school techs test an alternator by quickly removing the neg. battery terminal, and watching the stall and/or hesitation - can this actually damage the vehicle's electronics?
ОтветитьNew battery and new OEM Alternator been replaced couple of days ago, all interior exterior light more brighter, but when I depress the gas pedal with no significant load expect vehicle interior light on the light gets brighter for half a second and the volt gauge on the dash still shows drop on voltage, any idea why I still have volt drop please?
ОтветитьIf we can expect to see a voltage drop of no more than .5 between positive bat and stud of alternator, what is the benchmark voltage drop we are looking for between the housing of altenator and negative bat?
ОтветитьGood to see you brother. Good topic and appreciate all the work you put into the videos. 👍😁
ОтветитьAnother great video man. Thanks for the knowledge. 👍
ОтветитьWould have been more informative, if we had a vehicle that would start and run to do the test on. It would have been more clear to me and others. Maybe have a re-run of this video with a good vehicle.Thanks for the video.
ОтветитьAmazing! I did not know that... Brilliant explaination!
ОтветитьMan, lots of new videos lately. That new garage ain't gonna pay for itself!
ОтветитьWow, suddenly now you increased subscribers to 1 million,what did you do?
ОтветитьI have been trying to learn this but nobody has explained to to me that makes sense. Still makes no sense. Less words more demonstration.
