Thanks. Are you getting an occasional red battery symbol light on or any other indication that your battery is not registered? I am seeing a delay in alternator charging by 1-15 minutes with occasional battery light. After the delay the alternator charges at 14V all day. Only delays during first start of the day. Cycle repeats each day.
