[DML] Re: holding buttons - effect on electrical system



It is a "load" but the technical term for this specific type of load
is called "Locked Rotor Current". It is normally 2-3 times the nominal
running current load and is used in calculation of the starting load.
It is not meant to be a continuous load. Newer cars have either an end
switch to shut the motor off or a current sensing circuit. On
Deloreans it is "not a good thing" to run the windows bang up against
the stops. It puts a lot of stress on the lift mechanism. If you want
to see this just hold you hand on the outer door panel as you open and
close the window. You will feel the mechanism push against the door
skin! This is one reason the origional lift mechanism fails, it was
made on the flimsy side and repeated openings and closings against the
stops will fatigue it quickly. Try not to run all the way up and down.
