(2) How to check the air conditioning system with the needle of high low gauge
To connect with manifold pressure gauge can find the cause of air conditioning system.
Because manifold pressure gauge is various sensibly (Ambient Temp. is based on 30~35 °C)
Caution: Operating E/G RPM 1500~2000 is must, and so to that you can check the correct cause and air
conditioning. (In case below the figure of indicated pressure gauge has some clearance, confirm with
approximate indicated needle data.)
