those eikon are not ment to run rotary only coils-they cause power fluctuations and can some sometime cause power spikes which will burn out your motor.
get the latest model or the non meter critical.
Or get one of these they (have been using one for years)produce clean high volts,low ripple and noise and alot of amps will make a rotary and coil run very smoooooooth and will also make the motor last longer.
