Before ohming the contacts, it is critical to place the relay in the same position that it would be in when installed on the motor. Hey, bad accent or not, she still knows what she's doing in every other department of acting, much like James Woods, who is such a great actor that he appears to have gone full method and launched himself into space, which would explain where he's been the last couple of years. The start winding cannot experience any current flow because of the normally opened contacts of the relay being wired in series with it. Relays are used to switch starting coils in contactors and motor starters, heating elements, pilot lights, audible alarms, and some small motors (less than Vs HP). Current relays are often seen when capillary tubes or fixed orifices are used as metering devices; the reason being that systems employing capillary tubes and fixed orifices as metering devices will equalize pressures during their off cycle. All open loop control systems operate without feedback. But to me, the writing with a few characters and unbalanced tone is what really killed my enjoyment after awhile.
