Yes you should add oil before installing. Simple add 3oz for every pound of freon your vehicle requires for a full charge. Pour the oil directly into he compressor through the openings that the hoses attach to.

You did put 134a back in? But possibly not enough? There is a pressure safety switch somewhere in the system that detects pressure and opens the circuit if not enough freon. At least that is where I would start. Does the Compressor turn freely otherwise by hand? Did you get enough compressor oil into the system (new Compressors need special charge with compressor oil).
are you sure it's the alternator and not the AC compressor?
makes more sense if it's the compressor putting excess load when you turn on the AC system
maybe add a small can of oil via low side port w/ that r134a adaptor to see if the compressor is low on oil; that can be bought at walmart or any auto parts store
but really has to be evacuated and checked if correct oil level inside the system, which costs $$$
NOPE STOP CHARGING DONT PUT NO MORE REFRIGERANT IN SYSTEM.DO GOING TO DAMAGE NEW COMPRESSOR AND THE EXCESS PRESSURE WILL BUILD UP CAUSE THE REFRIGERANT CANISTER TO BURST EXPLODE INJURY OR FATALLY HURT YOU. BEST TAKE CAR TO A GARAGE.LET GARAGE PUMP DOWN AC SYSTEM AND CHARGE UP.BECAUSE YOU WILL DAMAGE NEW COMPRESSOR. MOST OF TIME I WILL HOT WIRE THE AC COMPRESSOR. MAKE SURE COMPRESSOR HAS 2 OUNCES OIL IN IT.IF COMPRESSOR START UP NO OIL IT WILL LOCK UP.DONT KEEP PUTTING REFRIGERANT IN THE AC SYSTEM, THE R 134A GOING TO FREEZE UP TOO MUCH MOISTURE IN SYSTEM YOU HAVE TO HAVE A VACUUM PUMP TO PUMP DOWN AC SYSTEM CHECK FOR LEAKS BEFORE CHARGING SYSTEM UP.LOW SIDE NEED TO BE 31 - 36 PSI THE HIGH SIDE SHOULD BE 165 - 205 PSI.
You need to also repalce the drier, make sure the compressor has the amount of oil required, vac down the system then charge with proper amount of r134a.
YOU TAKE TO A GARAGE LET THEM PUMP IT DOWN FIRST MAKE SURE YOU PUT THE RIGHT AMOUNT REFRIGERANT OIL IN COMPRESSOR.IT COME WITH SHIPPING OIL IN IT BUT YOU HAVE TO POUR IT OUT.PUT IN THE RIGHT AMOUNT OF REFRIGERANT OIL IN COMPRESSOR LOOK IN OWNERS MANUAL TO PUT IN THE RIGHT AMOUNT.NOW IF YOUR OLD COMPRESSOR SEIZED OR LOCKED UP THEN LET GARAGE FLUSH OUT METAL SHAVINGS OUT .IF YOU DONT FLUSH OUT SHAVINGS THE NEW COMPRESSOR WILL BE DESTROYED.ALSO YOU HAVE TO REPLACED THE ACCUMULATOR OR ORIFICE TUBE IF EQUIPPED.IF OLD COMPRESSOR DIDNT LOCK UP.PUT NEW REFRIGERANT OIL IN COMPRESSOR IT TAKE AT LEAST 1 OUNCE OF OIL BUT CHECK OWNERS MANUAL ALL VECHICLE HAS DIFFERENT SPECS.AFTER COMPRESSOR OIL BEEN PUT IN EVERYTHING ALL REFRIGERANT LINES TIGHT.TAKE VECHICLE TO A GARAGE THAT DO AIR CONDITIONER WORK.THEY HAVE TO USE A VACUUM PUMP TO PUMP DOWN THE AC SYSTEM TO REMOVE MOISTURE AND LEAK TEST THE SYSTEM WHILE IT PUMP DOWN.IF YOU DONT LET THE GARAGE PUMP DOWN SYSTEM. THE MOISTURE WILL FREEZE UP IN AC SYSTEM CAUSING POOR OR NO COOLING.THE GARAGE GOING TO CHARGE YOU TO PUMP DOWN AND CHARGE UP SYSTEM.IT WOULD BE CHEAPER TO DO THIS THAN TO BUY A VACUUM PUMP AND MANIFOLD GAUGE SET.WHEN DOING AC WORK YOU NEED SPECIAL EQUIPMENT AND TOOLS TO DO THE JOB OR THE AC SYSTEM WILL NOT WORK RIGHT.
will be ok compressor will not operate until system is gassed pulley will just freewheel . the oil will be put in when system is gassed a pressure switch in the air con pipe prevents it operating until at correct pressure
Look for the ac compressor,and locate the large ac line coming off the ac compressor.Follow it until you come to the ac charge port.this is where you charge it up with a charge hose that you have.Put the can on the can tap,and the quick connect to the ac port on the ac.Turn the t handle on the can tap clockwise until all the way down.hold the can upside down.start engine and turn the ac on high blower.and recirculate.shake can lightly,until the can empties.Turn the t handle counter clock wise,almost all the way out,and remove the can .Repeat to add another can,Don`t put too much freon in,and add ac oil also.If it lost freon,it lost oil,failing to do this could cause the ac compressor to lock up.One 4 oz can will be fine.look for the large ac line to get cold,and the accumulator to get real cold,then stop with the freon.
