Hello everyone. I have found this forum very helpful in the past with my Expedition and decided to join with a new problem at hand with my 1991 E350/RV. The dang thing won't keep running. I had both batteries changed and now am the proud owner of a new alternator yet it still will not charge the batteries. I am sitting here with a 12000 pound machine that doesn't run for more than 50 miles now and am completely confused. I did have a look at the alternator after it was put in and it seems like the belt is quite loose. It does turn when the engine is on but something tells me this is a problem nonetheless. I will have to take it in for a look see but am asking for any input on what I am looking for. This is my first RV and only had it for a month. I inherited it from my brother who no longer had need for it and he said it has not had this happen before so what do you think? If you need more info please let meknow and I will get it for you. Thanks in advanced, Pete
