Starting Capacitor size for a 220v, 50Hz 2.5 kw water maker high pressure motor

Jose Venegas

The water maker high-pressure pump motor is not starting and breaking the AC circuits of shore power and Onan Generator.  It is a LeRoy motor. I have checked for a short circuit and seems OK. (1-ohm resistance between poles and 12.5 Khoms from pole to the earth)  The starting motor capacitor specs are not visible.  I measured  48 micro F, which seems small for the motor size.  Does anybody know if that is the proper size?  The motor makes a very short humming sound before the AC circuits jump.  Before I remove the motor and proceed with major surgery, I would like to know if the capacitor is the proper one or has failed.

Thanks in advance
