Charging system issues
I have a 2000 ford windstar, the battery light on the dash came on awhile ago, and the van soon wouldnt start. I put a borrowed battery into it ... but needed to jump it to get it started, then i tried the "classic diconnest the battery method" to test and see if the alternator was the issue.... it appeared that it was, as the van stalled out. I bought and installed the new alternator, but the problem was still existent, however... when the battery was disconnected the van still ran... so I bought a new battery, my issue remains... the battery light on the dash comes on. I still have a weak charging system. Does anyone have any idea what else could be causing this issue? thanks in advance for your much needed help.

Re: Charging system issues
Welcome to the AF Forum!

When engine is running, check if you have the same voltage on the B+ (positive) connection of the alternator and the positive of the battery. If you have a even a slight difference, it means that you have a bad contact. I think you may have a discharge when you car is turned off. Maybe a short-circuit somewhere. Disconnect the + terminal of the battery and connect an amperemeter between the battery and the cable. If the current is more than 50mA, you have a short somewhere.
