Thank you, but.....

I have a digital mutlimeter. I know that i have to switch it to ohms, but how can i tell if it has resistance or not?

You have to lift one leg of the resistor out of circuit then swith the meter to the ohm setting and touch the meter leads to the resistor if it doesnt register its open and the resistor will need to be replaced.

What does it mean if the pressure switch shows it has ohms on the pins


Ohms is a measurement of resistance but there are some things that you should know. One is the wires on the meter can add resistance. This is not a big deal but in some cases it can be. The other thing is that it can measure you or the circuit that the device is installed in so it is best to use clips and not your fingers and you should take the item out of the circuit that you are testing if you can. Ohm meters have ranges and unless it is an autoranging meter, you can have it set to low or too high and cause a problem.

How do I measure ohms in distance


Ohms is a measure of resistance as in an electrical resistor. Wire also has very small resistance but a long length of wire can equal a fair bit of resistance.
Now, to your question, you can't measure ohms in feet - unless you know the resistance per foot of wire (as an example).

Dse q-1559 Digital Multimeter


hi ,my q1559 is doing exactly the same ,are you using a rechargeable battery that is pretty old ? My point is I put a new battery in and it disappeared . I don't know if this is your problem but try cleaning the test meter probes connector, because the audible warning is telling you have a test lead connected to amps post whilst the switch is not turned onto measure amps..I used a cottonbud it fits perfect soaked in contact cleaner.

How do you check an automobile Ignition Coil on a 1973 Datsun 240 Z when the ignition coil is't connected to the automobile electrical system? Can this be done? If so please tell me How!!!!!!! THANK YOU...


    1. To check the coil's primary circuit, perform the following:
    1. Make sure that the ignition switch is turned OFF .
    2. Remove the primary wires from the (+) positive and the (-) negative terminals of the coil.
    3. Using an ohmmeter, set it to the 1.0 ohm range, then connect the probes to the primary terminals. The resistance should be 0.84-1.02 ohm's; if not, replace the ignition coil.

    1. To check the coil's secondary circuit, perform the following:
    1. Make sure that the ignition switch is turned OFF .
    2. Remove the coil wire from the center terminal of the coil.
    3. Using an ohmmeter, set it to the 15,000 ohm range, then connect the one probe to the center terminal and the other to the (-) negative terminal. The resistance should be 8,200-12,400 ohms. If not, replace the ignition coil.

    Oil light on.changed oil,filter,and oil sender.


    the big question is, do you have oil pressure on your engine? If your engine has no oil pressure, the lifters (tappets) will clatter loudly. There won't be any doubt that there is something wrong. As long as your engine sounds normal, something is probably telling a lie.

    Now, to test the sending unit, connect a DVOM (digital volt ohm meter) to the sending unit and the a good engine ground. Put the meter's function switch in OHMS , R X 1. You should show infinite resistance. Now, start the engine, you should show zero or very low resistance. If you don't know what "infinite" resistance looks like on your meter, with the meter set in the correct function position, touch the meter leads together. This is contineutity or zero ohms. Now, take the meter leads apart. This is infinite ohms or an open circuit reading.

    If you sender is working, you need to trace the wire and look for a short circuit grounding the wire somewhere. If you are still unsure, take the sender unit back out. Start the engine and allow it to idle for a few seconds and pump a few ounces of oil out. Shut the engine off and reinstall the sender. This is how you break a "air lock" in the oil pump. These are common on Softail and Sportsters but not some much on you RK.

    Good Luck

    I have a older toastwell commercial single belgin waffle maker. It do not heat up at all. How can I test it? The wiring seem pretty basic a couple of junction boxes and it looks like some sort of small...


    No problem using a multimeter set it to OHMS x10, or if digital just OHMS, now anything with an element is basically a "load" on the end or a pair of wires, with a switch, maybe thermostat IN the Phase line, that "breaks" said line, when turned OFF, OR Temperature is reached. So on the "Cold side of either, the switch, or thermostat, and Neutral, check to see if you have a resistance? This resistance will/should be the element. There should be NO Connection between either "Pole" of the element to the Earth/Case, Earth on Cord. Check the Power Switch is Opening and Closing indicated by a "Short Circuit" Zero OHMS, when ON, & "Closed" and Infinity or "Open Circuit" when "Open" or OFF. Sometimes these units will have a thing called a "Thermal Fuse" this is a small cylindrical device with stiff wire leads, it is wired into the Phase line, and when it "Blows" due to an "Overheat" situation, it becomes "Open Circuit", this needs to be checked as well, if there.. Now to tell if the "Resistance of the Element is correct.. you need to do a bit of math... You take the Wattage,and divide it by the Voltage the it is operating on... Then you take that answer, the Amps, and Divide it into the Voltage, that will give you the Resistance of the Element, +/- 10% is OK. EG: 3000 Watt toaster.. Voltage 120 Volts, therefore = 25 Amps, that 25 Amps, divided into the 120 Volts, = 4,8 OHMS, that is what your Element should read if it is OK. (+/- 10%). Check continuity, from Prongs of the Power Cord to the termination in the unit. Check for "Shorts" & "Dis's" (Open Circuit) and "Continuity" & "Resistance". Also draw it out as you go.. this can be real helpful.

    I have a amp with switch that says high power & high current


    The ohms rating measures the electrical resistance of the subs(impedance). On the subs there is usually a label that tells you what the impedance is for that particular sub,example= 4 ohms . The only way you can get to a 1 ohm load or less with a pair of tens is if each sub has dual voice coils that are 4 ohms each wired in parallel. Generally Sony xplod's are a single coil 4 ohm woofer-yours might be the exception in this case .To figure out your resistance say with 2 subs that are 4 ohms you have to know how you intend to wire them for instance if your amp puts out a fair amount of power @2 ohms and thats the number you want to hit than you will want to wire the subs in parallel( + to + and - to -) wiring in parallel lowers the resistance.(ohms) If you want to hit 1 ohm and you have dual 4 ohm coils then wire all 4 coils in parallel and that will then be a 1 ohm load. Its simply a matter of dividing the ohms by the number of speakers that you intend to connect. if you had 3 10s that were 4 ohms each and you wired them in parallel the ohms would be 1.33 (as 4 divided by 3 is 1.33)(4 divided by 2 is 2) (4 divided by 4 is 1) On the flip side wiring in series will raise your impedance-a pair of 4 ohm subs wired in series gives you an 8 ohm load 3 subs gives you 12 ohms and so on. I wouldnt worry about the high current switch unless youre planning on taking it down below 1 ohm which it sounds like you arent currently set up for.

    No Spark 1992 toyota camry


    you should also check the crank position sensor this is what tells the ecm when to spark. this is a prox switch and when unplugged and checking ohms while cranking you should see a sqaure wave. should go from 0 ohms to infinity. when these go out you will not get any spark on any cylinder

    I was wondering about the life of my plug wires,so I would like to check the Resistance with an ohm meter to see if they are still in spec. Does anyone know the ohm spec? Thanks Mike P.


    Don't know the actual resistance but the general resistance I use that has not let me down is 1000 ohms per foot and not more than 10,000 ohms on any wire.

    Preheat takes forever


    http://www.applianceaid.com/nuker.html
    click the link  Oven temp sensors sense the temperature is the oven cavity and the temp sensor changes resistance, this change in ohm resistance tells the oven control what temperature the oven cavity at and tells the control to shut off the element or turn it back on. The most common temp sensors used today ( *not all ) are approx 1000-1100 ohm resistance at room temperature ( 70�F )
    Some ohm readings and there temperature:
    Degrees F    -   Resistance
                100 - 1143 ohms
                 200 - 1350 ohms
                 300 - 1553 ohms
                 350 - 1654 ohms
                 400 - 1753 ohms
                500 - 1949 ohms
