Thanks Wayne!
I have seen motor windings overheat and burn in just a few seconds of locked-rotor simulations - identical to what happens to an AC compressor motor when it tries to hi-head restart and encounters low voltage. Motor winding insulation can not tolerate repeated "almost to the point of charring" over amperage even on a momentary basis. The bright copper with translucent yellow varnish starts to change color, first to orange, then brown then (you don't want to know). One single burn spot (short) in all those windings starts the process.
Just because something "seems to work 10-times in a row" does not cut it in my book. Only accurate voltage and amperage readings taken at time of high head restart are valid. Many of you are financially comfortable enough to not have a crisis when an A/C compressor burns out after a year or so. I do not have that luxury. So boasting "my tiny generator starts MY air conditioner" is misleading and fraudulent - unless the boast includes "The inrush does not slump the voltage to 105 volts or less". I am not being picky here. I am attempting to warn other folks that there is more to choosing a successful power source than chortling "See! I told you so! It Starts!"
