Also posted this in aop. Not so sure which forum would have been best post. Thanks for any help. I am new to this sight and this is my first post although I have used you guys for help in the past. Anyways. I am working on a mcquay ALR130E. I keep getting an alarm of low oil/pwr on comp 4 and 3. Usually alternating and sometimes at the same time. Today circuit 1 is cutting off when comp 3 is activated. Little to no oil in sight glass on comp 1 and 3. Can't get oil to come back to compressors. Yesterday same prob on circuit 2 and circuit 1 was fine today circuit 2 is fine and 1 is acting up. Any suggestions or help would be great. Thanks
