It's a possibility the alternator isn't the right amp alternator for the van. In other words if the van needs a 110 amp alternator and a 80 amp was installed then it is not keeping up with it's needs. That will cause a low reading. Also the plug could be making only limited contact and that could also cause the low reading. My suggestion is to remove the alternator and have it checked at the local auto parts store. Also check to see that it is at least 100 amps, and replace that plug and you should be ok. GOOD LUCK!!!
