I'd like to know more about this, if you have time. The charger you linked to is 7.5 A peak, so what's this about an "early version"? How do you have this wired into the van? For example, how did you set it up so the radio runs off the house battery (downstream of the DC-to-DC charger) when the engine is off, but off the alternator when the engine is running? How do you connect the DC-to-DC charger's input and the starting battery to the alternator when the engine is running, but disconnect the charger from the starting battery when the engine is off? I'll come clean: I have extensive electrical knowledge and an avionics technician certificate, but I've never bothered to decipher the schematics of my '84 camper's charging system or understand how the GoWesty aux battery kit modified it. Sorry I'm asking this question without first doing my homework. Thanks! I added a couple of skeleton pages to the wiki, if you'd like to respond there: http://www.vanagonwiki.net/wiki/House_Battery_Articles http://www.vanagonwiki.net/wiki/Charging_House_Batteries_from_Alternator |
