Should you get a reading between the herm and fan terminals on a dual capacitor?

I would say yes because they share the same common terminal.

What does the volt on a capacitor mean?
the voltage number on the capacitor indicates that the capacitor can with stand to that particular voltage across it.generally during design, the value of capacitor will be selected in such a way that this voltage rating should be double than what really we get in the circuit
How do you fix the run capacitor on a ceiling fan?
Be certain to observe the exact same polarity as the old one. A capacitor does have plus and minus leads. Should an old defective ceiling fan transformer be replaced by a capacitor?
Test a DC capacitor?
Testing any capacitor can be done by simply shorting out the two terminals to discharge any existing 'charge' (start from scratch, aka zero basis), then connecting an ohm-meter to it to determine if it's capable of developing maximum resistance (charge build-up). A discharged capacitor will have zero resistance (dead-short, zero ohms), when it is discharged. It doesn't matter if it is AC or DC. When you apply voltage (put the terminals from your ohm-meter to it) across the leads, it should quickly build up resistance. If you have an analogue meter, it will read shorted, then should quickly sweep to infinity. With a digital meter, it's a bit more difficult as the meter will 'sample' every so-often, refresh the display, then show an infinity resistance... leading you to think wtf is it doing? This happens very fast, and most often what will happen is that within 1-4 seconds of connecting your digital ohm meter to a cap, it'll blank the display, and do nothing afterwards.... which means it's reached it's limits of impedance measurement. This a simple basic way to test a capacitor to see if it is 'capacitating'. There are more involved methods which involve T/RC to determine the actual value, but should be covered in detail in an appropriate forum.
If a voltmeter has one black and two red terminals how should it be connected?
ok if there were 100 people and there
Why should you use process of synthesis during the post reading phase?
In order to make connections between pieces of information (APEX)
What should be pressures for 3 phase condenser?
Pressure is equal to voltage and is the potential deference between the capacitor two terminals
What does 200WV 470uF mean on a capacitor?
200WV is the working voltage of the capacitor. This is the value that should not be exceeded between the two terminals. 470uF is the capacitive rating of the capacitor. It means 470 micro Farads, or 0.47 Farads.
How do I test the alternator on a 1999 Pontiac Sunfire?
Connect a voltmeter across the battery terminals without engine running reading should be around 12.8 With engine running reading should be 13.8-14.2 if you are getting these numbers alternator is charging battery
Is 24.0 mfd a good test reading for a 24.5 mfd run capacitor with a multimeter?
That would depend on the tolerance of the capacitor. As the measured value is only about 2% below nominal and most capacitors have 10% or 20% tolerance it should be fine. However if it was a precision capacitor with for example 1% tolerance it would be bad.
What type of capacitor should be charged slowly after not being used for a period to prevent damage if a sudden surge?
if exact replacement capacitors are not available,you should substitute it with a capacitor that has
Which Capacitor should be connected in one direction?
The electrolytic capacitor should be connected in only one direction.
How do you test a 3 phase capacitor?
Observe safety precautions when dealing with electricity. Capacitors store electrical charge which can be fatal for a time after they have been disconnected from electricity source. The following should only be carried by a suitably quilified person. Isolate electricity from capacitor. Wait a few minutes to discharge. Measure capacitance between phases with a capacitance meter. Connect suitable amp meter to each phase of the capacitor. Reconnect electrical supply and measure current on each phase. The values for each phase should be similar but could be slight variations depending on condition of the capacitor. Compare these values with the rating plate information. The amp value decreases as the dielectric value of the capacitor decreases indicating the deterioration of the capacitor.
Why should you keep the oil terminals?
Oil terminals? What is an oil terminal?
Should your capacitor have continuity?
no
How do you discharge high dc voltage capacitor?
When a capacitor is powered off in an energized circuit, the capacitor still stores a certain amount of electricity. When there are other loads or components in the circuit, they will slowly discharge, or they can be quickly discharged by short-circuiting with small resistors or wires (at low voltage). When the capacitor discharges, the two poles of the capacitor respectively carry a certain amount of charge, and the outside world and the capacitor form a closed loop (generally, the closed loop does not include a power supply). The excess electrons (negative charges) approach the positive electrode of the capacitor to form a current, so that the charges at both ends of the capacitor are neutralized. When the neutralization is completed, the electric field between the two electrodes of the capacitor disappears. However, this is in an ideal situation. The amount of terminal charge is exponentially neutralized towards zero, but not zero. Discharge requirements of capacitors After the capacitor is disconnected from the bus, it must be discharged through a discharge resistor or a special voltage transformer. Discharge should be performed between the lead wires of the capacitor and between the lead wires and the casing. The capacitor can be grounded after the capacitor is discharged. Before working on the capacitor, be sure to conduct a test discharge. This discharge is to place the discharge rod on the terminal of the lead wire of the capacitor for a period of time. Even if both sides of the capacitor device are grounded, in order to prevent residual charge on the capacitor, a test discharge must be performed, and each group of capacitors connected in parallel must be discharged. Special care should be taken when conducting inspection discharge of capacitors removed due to faults. Due to the damaged capacitor, the general grounding device may not function as a ground discharge due to a partial disconnection. If the capacitor device has an interlock device, it should be considered that only after the entire device is grounded, the small door of the capacitor bank protective fence can be opened.

How do you test a tps on a 1990 miata?
The TPS on a 1990 is a WOT switch. Using a multimeter set to read resistance, or a continuity tester, check the resistance between the center and bottom terminals of your TPS with engine off and throttle closed completely. You should read continuity (or zero ohms) between those two terminals, and if you manually open the throttle slightly, the continuity should be lost (resistance goes to infinity). A complete test takes more time; the manual states that with a 0.016" feeler gauge between the throttle lever and the throttle stop screw, you should read continuity, which should go away if you put a 0.027" gauge in there. With the throttle fully open ("WOT"), there should be continuity between the top two terminals of the TPS. In between the idle and WOT positions, there should be no continuity between any of the terminals
When checking the high pressure cutout switch with an ohm meter there should be continuity between?
terminals one and two
