I'm posting this for a friend of my fathers. I will pass along any posted suggestions. The problem as described to me:
"Car: 1992 Passat 16V 95K For 18 months it has had a strange electical problem. The local VW dealer has had the car for 2 long stretches with no success. Suppose the car to be started normally. After 15 miles or so, the electrical system will begin to fail as the battery discharges and shortly the car will stop. After waiting awhile it can be restarted if the battery and engine aren't too cold. Clearly the battery has not been charged (net that is) since starting. Now suppose that the car be started and IMMEDIATELY the throttle punched a couple of times, revving hard, to about 4000 or more. Then the problem described in the preceding paragraph does NOT occur. The battery charges normally and the car runs normally on the alternator as long as one likes. Attempted cures have included 3 different alternators, two from VW and one non-Bosch equivalent. No change, same problem. The VW dealer has run a standard set of diagnostics on the electrical system. Also, it doesn't appear to be a belt problem. A minor oddity is that the battery charge light never seems to come on. What seems to be happening is that something in the charging circuit is activated after starting ONLY when there is a big enough raw voltage from the alternator to trip or trigger that something. The only obvious electrical oddities are the electrical cooling fan runs a long time after shutting the car down, more than 10 minutes. And only one electrical window goes up at a time."
