When the window reaches the end of its travel, it stops.... and so does the motor. By holding down the power button you are supplying power to a "stalled" or stopped motor which causes it to "draw" much more current than it does when it's moving. (Has to do with back EMF.) So you are using a lot more current which puts a strain on the electrical system. The large current causes a drop in the system voltage and thus the dimming of the lights. 4. holding buttons - effect on electrical system Posted by: "daviddelorean" daviddelorean@xxxxxxxxx daviddelorean Date: Sat Feb 9, 2008 3:40 pm ((PST)) Why is it that when you continue to hold your electric window buttons after the windows are in position, the volts drops sharply and the headlights get dim. This isn't just on DMCs but all cars. Thank you, Dave Delman 1981 Electric DeLorean Project electricdelorean.com **************Biggest Grammy Award surprises of all time on AOL Music.
