Or if you dont have a dual input scope, at least run the output through a large parallel capacitor before the batteries, and measure between this cap and the batteries.

Also, has anyone used caps back to back for a long period of time successfully?

The higher the capacitance the lower the frequency required before the capacitor starts to act like a wire link in the system.

While the cap might not be getting hot, it is shorting out all the lines to the mill (at a point on the sine wave). The better the ESR (equivalent series resistance) of the cap the better it will handle the shorts, but I don't believe caps were designed for this type of torture.Edited by Haxby 2008-09-03
