If you parallel across a switch you will get a 0 reading with power. The meter acts as the resistance for the voltage , can confuse the hell out of people ……. That’s why hopscotch method is best practice , always grab the neutral in circuit and move along each component like in video . Great 👍 video CHRIS
This dude is a beast!!!!!! These latest videos he’s been making and book is something new been following for years and it just gets better and better with time
Not here for the HVAC at all really although nice to learn. 😂 I just came for the AC voltage testing refresher as I’ve been living in a DC voltage world for so long. Great instructional video made easy to learn and not too rushed. Outstanding! Excited to subscribe and see more! Thanks!
@@fleurdebreezeacheatingllc2573 - the best way to encourage someone to do something is tell them to stop. I understand you are limited in your ability to figure the simple things in life. The best thing to say is nothing. But then, there’s always a stupid like you
With method 3, if you see a voltage across the switch that is also an indication of pitting and corrosion on the contacts. Actually more reliable than testing the disconnected switch since the resistance may be higher with the higher operating current flow. This is more significant in low voltage circuits as losing 5 or so volts across a switch has more impact at 12 or 24 v than at 120. But even at line voltage that voltage drop across the switch with load current is heat in the switch and lower operating voltage for the load, both of which will likely mean failure in the future.
He doesn't apply voltage to the 120v side where his meter is connected. He was just checking continuity through the switch. But yes I believe you are correct, you don't want to check ohms while voltage is applied.
That's curious you made a statement that the method of reading across the switch is use the least I use that method all the time. Maybe it's because I work primarily on commercial equipment
HVAC Switches: 2 wires = ON or OFF...When switches are OFF you got voltage between 2 wires across to the switch, needless to say switch is Open (24 or 120 volts) when switches are ON there would be no voltage (or very little voltage or OL) 😎🤞😂 Note: When measuring a live wire with a multimeter voltage there would be no voltage between 2 points close to each other. Takes me time to comprehend this switch rationale - when switch is OFF there would be voltage across terminal but when ON there would be no voltage across terminal.
I just got a new 24000 btu York side discharge....................When i stan in front the air flow is direct by the fan inside the condenser.............Is it normal??? when i saw a Trane side discharge or a Carrier the air flow goes outside by the fan.. I think it is very dangerous for a personne with long hair, who can have his hair stock in the shaft of the electric motor!!!! Sorry my english is not very good. The technicien wiil come back tomorow
