Truma Water Heater/Magnatek Converter
Had been contemplating installing a Truma water heater for sometime and finally took the plunge. The unit works as stated on demand continuous hot water. We did have a 10 gallon Suburban DSI unit before which work fairly well if we watched our shower time. Well not all went as according to plan. The unit worked fine at the dealership running of batteries but when I got home and connected to shore power the unit would show an over voltage fault. Time to trouble shoot........found that the convertor was putting 6 volts AC in to the DC circuit. Probably a failed diode or bad capacitor. Explains a couple of other funny things that I noticed on the DC indicator light panel. Got on line and did a little research and found that the Magnatek convertor is no longer produced.
Odered an upgrade from Best Convertors and installed, even came with a three stage battery charger. All is working as it should and I am glad that I caught it now rather than latter as it could have damaged other 12 DC equipment.
