What should be the ideal resistance when testing an AC pressure switch for the compressor in a car?
The ideal resistance when testing an AC pressure switch for the compressor in a car depends on the specific make and model of the vehicle. However, there are some general guidelines that can be followed.
For most cars, the ideal resistance will be between 0 and 5 ohms when the switch is closed (compressor on) and between 10 and 15 ohms when the switch is open (compressor off).
If the resistance is too low when the switch is closed, it could indicate a faulty switch. If the resistance is too high when the switch is open, it could indicate a problem with the wiring or the compressor itself.
It is always best to consult the manufacturer's specifications for the specific vehicle being tested.
