i have been in the electrical and refrigeration industry for 10 yrs now and have never herd of a "quick start" i have herd of and used many "hard start" devices however i have never seem them used in this way.they are wired across the compressor capacitor terminals to raise capacitance on compressors that trip the O/Ls during start up.also i have read you can raise capacitance up to but no more than 10% without any long term damage to motor windings.post back and let me know how this works in reducing the flicker effect which by the way is a very common problem.
