Hello Cal,
You seem to be very knowledgeable on the Monarch 10EE with the older DC motor generator set up. I work for the Navel Research Laboratory here in DC and have the privilege of taking responsibility of a 1954 machine that I swear has few hours of real operation on it, there is dried cosmoline on the half nuts – it’s never been engaged!
To the point – the motor will not go above about 200 RPM; start in low speed and slowly turn the control knob the motor relay trips out, contactor click - click, off, on, off, on… It seems as the smaller contactor (anti plug?) drops first then the motor contactor, happens in either direction, runs all day long at lower rpm.
The only book I have is for a later model that has more electronics than this machine, other than oiling and what lever does what it's useless. I am picking up a correct one this PM from a friend.
Thank you for your thoughts and time.
