Our family just bought our first Airstream. This is my first post. We purchased a 1973 Tradewind form a widower. It wasn’t set up to check the systems prior, and that was ok with us since we like the idea of going through it all and upgrading as necessity, time, and money allows.
The first thing I did when we got Dustie home (That’s her name, the previous owner named it after his daughter and put a nice decal on the side, we’re keeping it. Part of the story ya know?) Anyways the first thing I did was plug in the shore power. There was no battery. The 120 worked with shore power the 12v
did not. I then hooked up a 12v
battery charger and the 12v
worked. So I went and bought a deep cycle battery and hooked it up. 12v worked with and without shore power. A fan was left on, drained the battery. Shore power causes the Univolt to hum but doesn’t charge, 120 works. No breakers tripped, no fuses blown. My conclusion is the Univolt is not working on the 12v side. Sooo…
Looking at converters I see the Progressive Dyamics 4045 and the 4060.
If I take out the Univolt and breaker box will this work as a replacement for the entire system?
If so… for $25 bucks more should I get the 60 amp or is it necessary?
I am assuming the 12v distribution system is inside the Univolt is this correct?
Finally whats the difference between these two converters? See following links
Thanks for the help, and for all the great information I have gleaned from you all so far as well!
