There is a fairly straightforward way to check your ACR:

While connected to shore power, check the battery voltage of your house battery bank. It should be 13.5 or greater. Then check the start battery voltage. It should also be the same as the house which means that the ACR has combined the two. If not, either the ACR is bad or you have a bad connection.

If the house bank is below 13.5 after charging overnight, then it is likely that your charger isn't working right.
