As a first try, I'd put the 4mfd cap in series with the black-red coil, but I'd also bring it up with a powerstat in case I'm wrong. If it runs weak and hot, move the cap to the other winding. Which ever runs cooler and with more torque is correct. > > _______________________________________________ > Emc-users mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/emc-users Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
