Both VMs had 9v batteries that were low and read 5v - - 4 v low. The meters measured my trailer batteries at 16+v, but the batteries were really correct at 12+ v (a 4v difference). What was my clue? I took the meters over to my truck and also read the same16v. that I had on the trailer.

Not sure what the moral of all this, but obviously you can't trust a digital meter to be absolutely accurate. I'll have to keep my eyes open for a good reliable replacement for the two that I have.

Thanks to all you for your advice.
Thats good Tank,

I was worried that those nearly 17 volt batteries were going to explode! Glad it was just a multimeter problem as od as that seems. Good idea checking it with the truck.
