Having troubles with 1997 chrysler plymouth grand voyager van. It has about 112,000 miles on it and a 3L V6 engine. In general, was driving one day and lights on the dash and clock started flickering. This became more predominant until the vehicle actually died in the middle of the road ( about 5 miles later). This was followed by a constant clicking noise and the battery eventually dying ( believed to be a bad alternator which drained the battery). Had just had the battery replaced in January! So was felt to be the alternator. Had the alternator replaced but within a few days the electrical warning light on the dash returned. Vehicle seemed to be driving fine otherwise. This light would go on and off over the next several days until became constant. Took back to mechanic ( more of a body repairman) and had another alternator put in. Van lasted a week, if that, with electrical warning light back on and it again dying on the road. Same symptoms as before with unable to start, constant clicking and then battery drainage. Uncertain if should junk at this point or attempt to have repaired. Other possible problems ?? Anyone with similar experience, advise or recomendations? Thanks

Is your mechanic making electrical checks at the alternator to see what is missing? The alternator's field is controlled by the internal regulator inside the ECM. There is no voltage regulator inside the alternator. If the ECM isn't controlling the field for some reason, that can result in a discharged battery.

I thought it was one of those. Must get some charge if it lasted a week but not enough,

Why do you think the BCM on this van is causing the problem?
