What do you mean by Compromised Voltage Source? Compromised meaning what. The Loose Connection has a resistances but what type of resistance is this called? Corrosion Resistance = when there is a " series resistance" between a wire connectors. The Corrosion resistance will have a voltage drop between the wire male to female connectors

I think what you mean is you're not supposed to get any reading at all on reversing the probes or do I misunderstand

Why is red on common and not black

Solid unit for price point

The LoZ mode was new to me. I learned something!

Good job sir.

I have a Miller ruffneck welder it has 11 didoud how would I test them

Thanks for this video! I went out and dropped 30 bucks on a super cheap multimeter, then found it didn't have a diode testing setting, and thought I had thrown my money away. Hooked it all up to a breadboard and a 9V battery as shown in this video, and was able to successfully test everything, despite not having a diode testing setting on the multimeter. Was about to head to Lowe's to get a higher-end multimeter, but this video showed me I could test everything successfully even with my existing setup. Thanks!

Hi just found you and thanks for the fabulous video, I have tested some of my microwave diodes using your tester and it works very well but how do you test so called microwave double diodes (that's what it is called on the microwave schematic). The diode is made up of 1x HV-6X2P1 (double diode 2 rings) and 1x CL01-12 connected together at the anode end and testing using your tester was fine for the CL01 but for the HV diode it showed the same battery voltage in both directions, is there another method for these types of diodes to prove they are okay. Thanks

How do you replace the thermistor?

Nice explanation of ghost voltages

Silicon. Silicone is a whole 'nuther thing 😊

good teacher and tester

Do you have a video on how to test an LED with a diode?

Awesome video and in proper english too !! new sub indeed!

May i can ask something i get some diodes from old crt tvs circuit boards i checked with multimeter and shows 0.585 are good or faulty?

You are reading voltage because you dont need a "solid" connection to read voltage across the wire. You just need enough continuity to see voltage between the 2 wires. Voltage is only half the story. The true test is that current flow test and when you put that bulb in, the current tried to flow but failed because you have a lose connection somewhere and that "lose" connection is not enough for the amount of current needed to pass thru. Kinda like a car battery, just because you see 12V does not mean the battery has the capacity to flow enough current to turn the starter / engine, as soon as you try to crank the motor, that 12V is GONE like your test did when you plugged the light in, then when you stopped cranking or pulled the bulb off, the voltage returned to 12V or 120V ... Same situation here, you got 120V but then tried to pass current and it dropped off because it can't due to a lose connection. As a lineman for an ISP we learned this very trick, just because you have continuity between 2 wires does not mean the current will flow. You don't need much continuity for that meter to see across it. That meter has a 9 volt battery and if the wires can support enough current flow to complete the circuit for 9V, you will then see the 120V across it. The true test is the current flow test. If it can pump current thru, then its a good circuit.

Thanks for this great video. Looking at 3:06 - my Fluke 113 drops from 9.4VDC to 6.5 when I add a known good 2.2K resistor in series. Your Fluke 115 shows 9.3VDC in the same situation. Is my meter causing this? Thanks again!

Thank you. Just diagnosed a heat-stressed switch on my fancy 10yo Kitchenaid microwave using this video. $3.16 part and a $220 Fluke 117 which I should have bought years ago. Worth it! I used Mouser Electronics for the part. Amazon is full of Honeywell knockoffs

This needs a lot more likes... Will the assist coil open the solenoid plunger without the hold coil energized? 😮. (I know the hold coil needs the assist coil to lift the plunger) but would the assist coil be strong enough to lift the plunger alone...if hold coil was open?

Great Review thank you!

This same scenario occurred with our microwave (capsule released from the screw base while removing it with the light circuit energized). The base shorted, but the end result is the HL won't light at all with an incandescent lamp. When an LED version of the bulb is installed it illuminates partially all the time but with an incandescent it does nothing. I assume there is some quirky failure mode of the triac. The PCA is a W10800189. Would you be able to identify which is part is the triac in question? Could it be one of the two TO-220 package parts I see? Thanks in advance.

Can you do more videos on schematics and do you have a course?

What voltage is the meter supplying to diode?

Man, I have one I need to return to fix. Had to replace both the main valve and the ice and water valve combo (all 3 had open solenoid coils). After the replacement, I was called back because when she used the water, the ice maker dispenser would try to fill with water. Thanks for the explanation.

Just wondering how a faulty door switch can cause the fuse to blow on a microwave oven. My Frigidaire oven fuse blown twice and I am going to check the door switch.

When talking about the neutral, everytime you said upstream, I was thinking downstream because I imagine current flowing from the circuit breaker to the outlet on the black (hot) wire and coming back to the panel from the outlet on white (neutral) wire. But we're talking about AC, so I guess upstream of the outlet is the panel.

I think a $10 analog multimeter can detect this ghost voltage too.

Great Video. Thanks for posting.

I just got my Klein cl800 because of this vid.’is there a way to increase the volume of the tone??

You’re the man Steve!

Great video! Thank you!!

A lot of work to do that review. Thank you

Steve, I might not know my terms, but isn't the forward voltage drop on the good diode about 2 V, not the 7.4 V that you stated in your narrative? I believe you misspoke. Thanks for this helpful video. Sincerely, Pete

What voltage would be measured at the main valve? Would it be 60 VAC?

👍Thank You! Very well done. Your demo/presentation made this easy to understand.

In the section “compromised voltage”, I could either test the outlet as is in LowZ or test the outlet regular but under a load to see the voltage is not reading 120 as it should?

So it has a lower input resistance…which forces the circuit to supply current. I’m having trouble with this concept. Can you explain it any other way?

Thanks for a thorough review. This seems to be the best clamp meter for those who don't need a Fluke to reinforce their manhood. The cost is less than a moderate dinner for two.

Can zener diode be tested on a panel directly like flyback diodes ?

Thanks for sharing.

I am using this exact switch to control heat on a nichrome wire set up. I don't have an indicator light so I am using my volt meter. I get no voltage even when the switch is on. Have I broken the switch? I did twist it both ways.

This is the best explanation of the loZ function of multimeters and ghost voltage I've ever seen! And more. Thank you very much!

Good info, I'm not the most handy with electrical components, I believe I need the door switch replaced, but I don't know if I need the normally open or close. When I start my microwave, it trips my circuit breaker. Can you please tell me which one I need, please? Thank you.

What if the fan and turntable work, but the countdown won't move and food won't heat? Thanks for this great video

I don't have a loZ meter. I was troubleshooting wiring at my brothers house. The new LED lights in the Kitchen stay on, but are very dim when the switch is turned off. The house is very old and the wiring is messed up. The hot for the light stays hot. The neutral gets switched. We have no idea where the the how and neutral are spliced back. Would induction be enough to dimly light an LED bulb? We are at a loss.

Great vid, Thanks!

Great job, Sir! It is such a simple idea to teach schematics through a detailed walk-thru, yet I have not found another channel that follows your model in explaining schematics thru following the different scenarios especially using color coding. Straight to the point, no time wasting no verbal garbage. You simply hit the target 100%.

Terrific video! I don’t have a kilowatt meter to test my 5yr old GE microwave that powers on, lights up, turntable turns but no heat. All door switches tested good with my multimeter. Also I replaced the control board which didn’t solve the problem. I’d appreciate any assistance. Can I assume it’s the diode, magnetron or transformer? If so I’ll replace the microwave. Thank so much.
