The other day was returning home from work and pulled into the driveway. The engine was idling at it's normal 700-800 rpm amount and I pressed the buttons to roll both of the windows up.
Well I held the buttons a little too long and the windows reached the top of their travel and stopped. But the extra resistance of the window motors caused the engines RPM to drop to 400-500rpm and it held there for about a second before the engine could catch up.
I repeated this several times applying the electrical load to the allready rolled up windows and it continued to drop the RPM each time.
The battery is new and in good shape, does this mean that it is time for a new alternator?
