(2) How to check the air conditioning system with the needle of high low gauge
To connect with the manifold pressure gauge, one can investigate the air conditioning system.
Because the manifold pressure gauge varies sensibly (Ambient Temp. is based on 30~35℃)
Caution:
Operating E/G RPM 1500~2000 is a must, so that you can check the correct cause
and air conditioning.
