How to analyze any schematic for automotive simplified to detail for beginners part two 

Thank you I am trying my best much appreciated

I appreciate your comments very much

Thank you

Hey Joe I have a real brain twister for you I have a 1998 GMC Sierra shortbed four-wheel drive having problems with the headlights no high beams low beams come on and off when they want to and another thing the daytime running lights is the only headlights that work when it's raining outside I would appreciate if you could help me out

Thank you for your comment

Thank you so much Mr Tommy

Thank you for being a viewer and a supporter

Thank you for your if you viewership

Thank you for the compliment and being a viewer

If you need schematics for them you can go to Google put in the make and model and you should be able to download it for free

Yes any gauge with a capital A in it is an amp meter weather the negative or positive is connected depends on the positive going to the battery

If you want to measure an alternator you use a clamp meter which you just clamp around the wire as I have done in videos on Joe electronics schematics for Auto thank you for your question

@@Joeelectronicschematicsforauto Yes 4 sure just binge watching now! thanks

@@Joeelectronicschematicsforauto Thank you

You can go find the channel Joe electronic schematics

The symbols are available on one of the videos that I did look it up on the channel I go over the symbols on the components thank you

I believe you could try on the channel Joe electronics schematics for Auto then there's another channel automotive electronics schematics by Joseph

I just put it up and I didn't even put a description or any tags yet I have to do more work on the channel thank you for your comment

@@Joeelectronicschematicsforauto thanks. Your teachings are very meticulous, if you could restructure and package your content that would be awesome. I can't speak for others, but I myself will not and try not to get into the wirings even thou learning about them is cool. I'm trying to be a hobbyist mechanic and am more interested in making sure that a car is in relatively good condition and make sure that any repairs I could do is within my capabilities.. which brought me to your channel because I was trying to get a refresher on circuits but also importantly trying to discover whether reference volts are standardized (apparently not all sensors have 5Vs but I think I can get better intuition by understanding their functions, as you have explained in some video) what's frustrating is it's hard to find such values as reference volts on alldatadiy, as I tried to on one of their sample reports. It's messy and leads to confusion for first timers.. maybe if you could make a short video to get important and useful data from alldatadiy for hobbyist I think that would be helpful. thanks for laying things out again, really appreciate your content!

@@jingyitay6179 the the problem is with today's cars they are computerized fuel pump starter lighting systems and there's a certain amount of circuits you have to know and today's modern computerized vehicles this is why I chose to teach people the basics the foundation are they they can decide on their own how they want to approach

@@Joeelectronicschematicsforauto Hi Joe, I understand what you mean. . but from this foundation can we know what's the reference voltage of the sensors? the only explanation I got why it's 5V is because that's the minimum voltage that the car can run off on (perhaps from manufacturer testing and also maybe from just analyzing the schematic diagrams?). So 5V is used as a constant for most of the sensors. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Ibuvo4Zz4rw.html

I'm trying to put links to my next ones thank you

The book is called automotive technology you can look it up on Google
