I am aware my Schaudt Elelektroblock EBL 264-7 can charge at around 14.4v and puts this voltage direct to the battery and all 12v services, does this voltage do any damage to any of the 12v bits in the van? My EBL is of course an old design so I wonder if more modern power supplies run at different voltages, 14v to charge the battery and a true 12v to the services. Every time I look at my EBL circuit diagram get an urge to fit a DC-DC controller to set the services to 12v.
