Re: '02 E350 Won't Charge
There's a draw somewhere along the line, that's for sure. Only thing I can think of is a bad wiring harness, or perhaps PCM, a bad PCM will generally bring with it some engine codes though. Electrical gremlins are hard to pinpoint. I'm sure others will chime in with suggestions but as you've done the obvious and had the system tested, a proper diagnosis should be done at a reputable shop.
