MY CAR DIES WHEN TO MANY ACCESSORIES ARE ON, WHATS WRONG?

2001 Lincoln LS • 89,000 miles

I can drive my car all day with just the heat and radio on, as soon as I turn on any other accessories the check charging system light comes on as well as the check advancetrac light. If I turn off the extra accessories the warning lights go off. The wipers and windows also operate very slowly while the car is running. Certain days I need a boost to start the car and then runs with same problems. What could be wrong?

Have the charging system checked out-could be the alternator

Bad diode in the generator. Have it load tested with a tester that measures "ripple". If ripple is high you are likely to also find the most output it will deliver is exactly one third of its rated capacity. That's barely enough to keep up with the fuel pump, ignition system and lights with nothing left over to charge the battery or run other accessories.
