Re: Bought a 155 today, now some questions...
About the window: When you push the button, current runs through the motor at a certain level. When the window is mechanically stopped by the door frame the motor stops as well. Current rises considerably, fuses would blow and heat would build up in the motor if the window management did`nt shut the current off, while you`re still pushing the button. That happens because the current runs through a shunt.
When a certain voltage is sensed over the shunt, a relay in which the current goes through is tripped, and you have to push the button again to activate the mechanism.
Now - the window guides in the door probably needs some attention, as the glass gets stuck somehow. Then the current rises etc. etc.
