Diode isolators for LD February 03, 2013, 03:27:19 pm Yahoo Message Number: 136632Hi Don I can't remember how I know this, but Lazy Daze switched from diode isolation systems to 'contactor' 12vdc relays to connect the batteries in parallel. In the old days, '70's and '80's this was a standard practice. The downside was that the contacts could stick (weld) shut and leave you stranded if both batteries ran down. Newer relays are better. I believe I saw this on someone's newer rig at a caravan club meeting. Possibly around 2007, so that might explain this instance. Maybe someone with a newer rig in the 2008 to present range could inspect their's and let us document that. RonB and 'Bluebelle a '99TKB.[Non-text portions of this message have been removed]
