Gentlemen,
feel like this is a stooopid question but rather than make a mess or create drama i prefer to defer to those more knowledgable.
while i have good experience working on, & bring back, defunct a/c systems, i've never tried to hook up gauges to a "charged" system.
in order to check my pressures & test my new, to me, gauges, i started with the high side hose.
as i got the connector on, & in the process of tightening it down, $hit started coming out the back of the compressor.
normal? am i supposed to wear gloves?
can someone please explain how to hook up a set of gauges to a charged system, what to expect when i do so, and how to check the high & low pressures?
i understand a/c systems, the numbers i'm looking for, which port is which, and all that. just a little clarification.
THANKS.
