Default Re: Possible Airstream Sprinter Westfalia Battery Charger Documentation

Besides the battery charging wires/cables for the starting battery and house-coach batteries, there is the remote temperature sensor wire and a set of sensor wires attached to the house-coach batteries. These sensor wires presumably read the voltage at the house-coach batteries and provide that information back to the charger which presumably adjusts the charging voltage up and down. The voltage set by the charger may differ from that at the battery terminals because of voltage drop and other factors. Thus some chargers have a set of wires to read the voltage at the battery terminals.

This is speculation that the Westfalia charger is set up in this fashion. If incorrect, please posr correct information. Thanks.
