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

["Elvis" <elvisnocita@xxxxxx>]

When the window reaches the end position, the motor gets locked,
can't turn anymore. In this situation a motor always draws
much more current than when running. 

much more current means the voltage drops a bit (depending on the
alternator, battery connection...resistance in the system).

Normaly there should be and end-switch. On one car I installed 
an aftermarket remote window closer from Toby that I modified
a bit to let it shut off when the current rises much higher 
than under regular use.

Current limiters are a common thing in the eletric motors businesse.
