Thanks to everyone who provided suggestions to me about replacing my 24 volt charger that just stopped working. I got some excellent suggestions online and offline. Newmar, the manufacturer of the original charger, has a $300 fixed cost repair option. Unfortunately, they stopped making my 36 amp charger a couple of years ago and would no longer fix my unit. That made the decision to fix or replace pretty easy. After searching around, I decided on using 2 separate IOTA 12 volt, 45 amp chargers and wire them in parallel to the 12 volt batteries making up the 24 volt bank. It was also suggested to have a way to swap the chargers every few full cycles in case there were slight differences in their characteristics. Excellent ideas - currently being implemented. The full price of getting 2 new chargers with all new cabling was about $400. The IOTA's come with a 2 year warranty vs the 90 day warranty of a repaired Newmar. Again, it was a pretty easy decision. Now all chargers are 12 volts and there is no special 24 volt one. I like that scheme better because it gives more backup potential. Thanks again for all the help! ==================================== Jeffrey Siegel M/V aCappella DeFever 53RPH W1ACA/WDB4350 Castine, Maine www.activecaptain.com The Interactive Cruising Guidebook ..
