6V92-TA Detroit Diesels
Boat has 24 volt system for diesels. Dash components are 12 volt, ie vhf radio, radar, depth, auto pilot. Unless the generator is running the 12 volt system doesn't charge. Was told it was made this way back then, newer boats have extra or 12 volt alternator to charge batteries. Seems strange to me. Is this correct? I know the alts on the detroits are 24 volts. Seems like there should be a inverter or convertor to step 24 down to charge the 12 volt system. Cant find anything in owners manual about this. Thanks! Where can u purchase the digital gauges in main control panel the 240 volts and amps and DC side from. They never seem to last, always go blank!
