2016 bx25d. alternator failed, battery died, tach and hour meter stopped working. Replaced alternator with new but tach and hour meter did not come back to operation. Turning key to on the tach needle goes to full and back to 0 as normal hour meter and other cluster indicators all do normal start checks but after starting engine tach remains at 0 and hour meter does not advance. checked connectors but not change. Any suggestions welcome.
