Ferroresonant Battery Chargers - Gord, on Jan 04, 2015 asked:

Thank you for your presentation last night. I started thinking that I may have a ferroresonant charger (which could account for some of the problems I have been having). The charger is a Newman RM 15 which was installed in 1990. I’m at “a bit of loss” because the manufacture’s manual says that the charger provides a float charge and will not overcharge. However, the schematic shows SCRs and it does not look like a smart charger. I thought that I would ask your opinion before I go to the expense of purchasing a new charger.

Galvanic Isolator Install Location – Rick, on Dec 15, 2014 asked:

I am looking to equip a galvanic isolator – where can I buy a Newmar Failsafe Galvanic Isolator? Is it critical to have it installed close to the shoreline connection? Is six feet too far away?

Ed, on May 14, 2012 asked:

I just re-read your excellent article on galvanic isolators. I was installing a "Smart Plug" on my PT 38 trawler and was horrified to find that I had one of those boats where someone in the past had simply not installed the ground wire. From your article, do I understand correctly that the isolator simply is installed in the ground line (ie. ground line from boat to isolator , then isolator to the ground connector of the plug)? You also mentioned having "fail-safe" isolators. How would I know if the isolator fails in the future, assuming failure is a possibility?

Pat, on May 02, 2012 asked:

I have a friend that is trying to get 12V from a 36V battery bank (i.e. he has six 6V batteries in series). He needs to get 12V for a heated vest (an accessory). Is there a diode or some contraption I could use after two batteries, and pull 12V from the bank? We would use one of the Newmar DC to DC converters, but they're out of his price range. Do you have any ideas?

To my surprise, the zincs on my Grand Banks 32 are gone after only six months of use. Before, they used to last some 18 months. Why the sudden change?
