No power from batteries - help

[Jeppo]

Hi there,

We are enjoying our 2011 Visa 19RSD, and I am also enjoying fixing things here and there since it helps me to know more about the trailer and what it means to own one (this is our very first trailer). However, there is a problem with the batteries that I can't solve and I was hoping to have your help.

Here is the problem: someone decide to still my two original batteries (which were working fine) and I needed to replace them with the new ones. These new batteries were fully charged and excellent quality (they were given to me by the dealership where we bought the trailer). They are two 6-volt batteries. After replacing the batteries, the trailer does not receive power at all from them anymore. I have checked all fuses in the box underneath the fridge, as well as all cables and connection (I thought that the people stilling the batteries might have done some damages to some of the connections). When I connect the external power and when the trailer is connected to the car, the display indicating the charge of the battery (the same display that indicates the level of water in tanks) signals a full charge, when the power sources (car or outlet) are disconnect the signal is "zero charge".

Any help/suggestion/comment that may help to solve this issue is really appreciated!

Thanks,

Jeppo
