Name and sketch the three types of plug gauges
the oil pressure light stay on whatever the engine fis running, and the oil pressure has been checked and it meet specifications: Technician A says that a ground in the circuit between the indicator light and the pressure switch could be the cause. Technician B says that an open in the pressure switch could be the cause. Who is correct?
When oil pressure is below the spring
pressure, the switch opens and the gauge
reading falls toward the low-pressure side.
Select one:
True
False

An adapter is required for using R-12 gauges on an R-134a system. A manifold gauge set is used when discharging, charging, and evacuating and for diagnosing trouble in an A/C system. The gauge manifold is designed to control refrigerant flow. When the manifold test set is connected into the system, pressure is registered on both gauges at all times. R-134a service hoses have a black stripe along their length, the low-pressure hose is blue, and the high-pressure hose is red.arrow_forwardTrue or False?
