LRA on this compressor is 11.9.
I need to know the running amperage in this unit as well as the hi/lo operating pressures.
At 10.5 oz of R-134a weighed in I am reading 1.0-1.1 amps and 0 psi lo side 75 psi hi side pressures.
The unit had a restriction.
I removed the filter drier.
Added sevive valves.
Did a nitrogen purge.
Replaced the filter drier and weighed in refrigerant.

I did see something I have not seen in all these years.
The compressor is on top of this box. The condenser cavity is dark(of course).
When I started the unit I noticed some arcing on the capacitor. Tiny little sparks and constant.
I shut it down to read the cap. Rated at 12 mfd and reading 10.2.(1.8 mfd less)
I don't like to see a variance greater than 10%.
I did not have another with me.
Upon re-connection I think it got a better connection,the sparks went away.

Hey ,what were the engineers smokin' when they set that condenser in there facing the REAR? WTF?
Ever try to clean one of those things?
5 minutes alone is all I need with those asshats...

In most cases,if it is difficult to do you are doing it wrong.
