The ohm readings across the three windings of a compressor should typically range between 1 to 10 ohms, although this can vary depending on the specific compressor model. The readings should be relatively close to each other, indicating balanced windings. If any winding shows an infinite resistance (open circuit) or significantly different values, it may indicate a problem such as a short or open winding. Always refer to the manufacturer's specifications for the exact acceptable ranges.
The RTD gives the temperature in resistance unit (Ohm), so you put the RTD in water with ice (0 C/32 F) and you take the reading in Ohm unit in your multimeter, then you put the RTD in boiling water and you take the reading in Ohm. Then you compare the readings according to the table for Temp vs. Resistance to check. It is important that water must be distilled, deionized. Tap water may give false readings as it has minerals. Instead of water test, you can you thermowell which are devices where you program the desired temperature for check RTD and thermocouples. Walter
Either add the two in series measured currents or find where they split or joined and measure the combined currents there. Kirchhoff laws.
OHM, who else?!

An ohm meter works by sending a small amount of electrical current through a material and measuring the voltage drop across it. By using Ohm's Law (VIR), the meter can calculate the resistance of the material based on the current and voltage readings.
If you have an Ohm meter you will want to measure the resistance (ohms) of the Primary and Secondary sides of the coil pack and compare your readings to the Specifications for the vehicle.

The " Ohm " is. 1 ohm is the resistance across which 1 volt of EMF appears when the current through it is 1 Ampere.
could be a few things, start cheap- make sure the metal is still on the rotary button, and that the contacts are on the distributor cap. These go bad quite often. if all is good there ohm out the coil. If all ohm readings are in spec then it is probably the unit inside the distributor.
1 mega ohm=______________ ohm?
