I don't have a gauge to check the high side pressure so I am not sure how high it is getting at this point.
I will check the voltage and I understand that the maximum amount of oil the system takes is 8 oz and I didn't want to over fill it so that is why I put 3 oz to start with.
The compressor is a rebuilt, but I won't be able to return it because I did the work myself.
I forgot to post the vehicle details too, 1997 Chevy Blazer, 4.3 about 153,000 miles.
