New Centaur 12V30A charger stays at 14.7V at very light load and zero amp load as well. A week later still at 14.7V. The batteries are two 4D batteries, starter battery and marine deep discharge in parallel. BMV712 and my other monitor both indicate zero amp in or out and 100% charger. Seems like it cannot get into float charger mode. Is this defective? Is there a dip switch setting which would exhibit this error?
