Run Winding 243V ÷ 2.6Ω = 93.4A Start Winding 243V ÷ 4.2Ω = 57.85A Well, THAT makes no sense, so they stop using Ohm's law and settle for believing that electricity is magic and Ohm's law is broken. In actuality, Ohm's law does work; it's just that the loads we measure tend to vary and don't all behave in the same way. Inductive Loads

Check the reading on the multimeter and compare it to the resistance specifications for both the primary and secondary windings. If the reading falls outside the normal resistance range, you’ll need to replace the ignition coil. A zero means the coil shorted internally. An excessively high reading means the coil is open.Oct 31, 2009 · The compressor sounds like the rod came loose from the pistion if you know what i mean. I just want to prove it bad. By doing an amp draw test or ohming out the legs to see if any are shorted to ground. I wanted to know the usual or common way to test a three phase compressor for a short, open or grounded winding.

I think that ohming out the windings of the compressor, would tell you just as much about the compressors ability to start as would a momentary jolt of electricity.The first thing to do before testing the windings of the motor is to remove the links linking terminals W2U2V2 and the disconnect the motor from supply (L1, L2, L3). A multimeter terminals placed across this matrix of terminals will indicate the following readings for a good 3 phase motor: (a) Terminals W1W2, U1U2, V1V2 will indicate continuity ...3 phase motor winding resistance values, Using Ohm meter: Disconnect all power from the system. Check all three wires singly T1, T2, T3 (three phases) to the ground wire. Readings should be infinite. If it’s zero or reads some continuity at all, then a problem is present with the motor or cable.The first step in troubleshooting noisy contactors is therefore to check the power input from the control source. If you think there is insufficient current coming in from the control source, you need to check its ampere rating to see whether it is high enough to pick-up and seal the magnetic coil. 2.
