Im a decently handy guy, but ive always struggled with electrical circuits and how to test. There are some REALLY good points made in here - well done guys.

I can't even BEGIN to tell you how happy I am to have found this video. I've been looking all over the internet to find ANYTHING that not only shows you how to use it, but explains why you put it on the settings that you do, AND what the readings should be. Trying to pick up a little here and a little there was driving me crazy. I can honestly say that I understand the BASICS of how to use my multimeter. Thank you, thank you, THANK YOU!

@Freedomquest08 6 лет назад

I use a mulitmeter so seldom that I have to stop and think twice about it each time I use it. These are good refresher tips for me regarding a very useful tool.

@et9443 4 года назад

Fantastic Video. I'm a DIY kind of backyard mechanic and pretty knowledgeable about numerous aspects of cars but I was always a little unsure of the electrical side of things and especially on how to test and probe for electrical issues. You made the information as easy as pie. Great job and I really appreciate it.

@kumara5492 3 года назад

Me too, a hobby mechanic likes to work on my car on weekends. Which volt meter will you suggest me , to buy, and from where?

@kathleenkelly4912 4 года назад

Thank you, Mr Matt Hagerty. I watched your video twice, and sincerely appreciate your clear description and teaching method. I carefully read through the manual upon purchasing my initial multimeter. A refresher course with a clear demonstration by an expert cannot be matched. Many thanks, and I wish you & your family good health throughout the high risk threat of Covid19.

I'm a mechanical engineer, but for whatever reason I struggled with circuits through college, and haven't needed to touch a mutlimeter or a circuit in 3.5 years. Excellent refresher, trying to diagnose why my truck won't start, problem is no power to fuel pump after full engine rebuild. Just got to figure out WHERE.

@davidrowe5822 6 лет назад

This is a great video. I'd like to see a follow up video that details real world situations with corrosion on bulb sockets. It would be great to see how to measure resistance in a socket that is corroded that explains how to troubleshoot older wiring that might be susceptible to corrosion. An explanation of resistance metering in more detail would be helpful for the DIY crowd that is trying to determine why, for example, a turn signal bulb is working but flashing faster than the other side of the car. Measuring resistance would be a way to determine that the circuit can flow electricity via amps and voltage yet resistance is higher than normal which might be the cause of why the turn signal circuit is behaving erratically. This just happened to me last week and I spent hours learning about it when I bet one of these awesome simple videos would detail a more real-world scenario. I can't say enough how much I learn from these Hagerty DIY videos. Thank you very much!

@Kaitozaki 3 года назад

continuity is also a great way to test a broken load...or switch...i always use it to check is my wires are going (+) positive and coming back (-) negative...before i hook up my 12v supply...you can also check which wires go to which switch if you have 3 wires on a 2 way switch...so you know which switch turns on the flow in the wire...

@rcadd1ct 6 лет назад

Using your fingers to hold the wires onto the test lead is a bad habit to get into. I was checking trailer wiring and a short made the wire get red hot. I got a nice brand on that one. It also trains you to get bit when you start working with AC circuits. Otherwise a lot of good info.

@hagertymatt8520 6 лет назад

rcadd1ct you’re right. I try to avoid it whenever possible, but loose wires on the table were difficult to wrangle. The other issue I’ve found is, testing high resistance circuits, my body can change the reading. Thanks for watching!

@matthewtyson4029 2 года назад

It turned out that the aftermarket air horn in my 2000 Ford Ranger XLT was not working due to simple corrosion of the horn’s terminals and the power wire to which they are connected. A quick cleaning using an automotive battery terminal post wire brush was the quick and easy fix for me to once again hear that sweet (but sometimes annoying!) ‘Wah wah’ sound emanate from my trusty light duty toy truck.

@BigLeo8772 2 года назад

Good video. The only issue I see is, during your ohms tests, you are holding the bare wire with your fingers. That creates a possibility of creating an electrical path thru the skin. Which could create a false reading if the path has less resistance than the component being tested.
