I resurrected a 19EA that had not run for 10 years, it runs good but only backs down to 400amps, FLA is 820. It seems to me it should go down below 300 at least.
I can't seem to find any min. load range figures in any factory literature.
I confirmed vanes are against internal stop. Any ideas before I pull the suction elbow to inspect the vanes? In the past I have had to hand fit vanes on 19D machines to get better fit when closed.
