Still monitoring this delayed charging problem during every start with the OBC Test 9 voltage readout. The delay seems to be getting less. The last three days the alternator kicked in less than 3.5 minutes, 35 seconds, and 35 seconds respectively. I am thinking this delay is not related to temperature which has been in the low 40's each morning. The battery light has not illuminated in a week. If I were not monitoring test 9 voltage I would not know anything different this past week. Will continue to monitor.
