1999 Windstar se do not start.

[Leandro]

My 1999 ford windstar se do not start. The battery is dead but the charging system and battery are fine. The system was reviewed by a technician and he determine that this ok. He change the battery by third occasion but few months after the battery was dead again.
I believe that it has a short circuit or some fault in the system, but to not even detected. Somebody knows that it can be?

You may have a dome or map light staying on.

check the brake light switch, it's known to kill batteries by accidently leaving brake lights on

Use a multimeter to test the amperage being drawn from the battery while the van is off. Pull fuses one at a time to see what is causing the battery to drain.
