Default Shore power

Nothing that runs off DC power will work when I'm plugged in to 110. What could it be?

Does it run on battery when not plugged in?

Check the 110 circuit breaker that feeds the converter section. Cycle it off then back on.

If that doesn't work check for 110 coming out of the breaker. If you are not comfortable working around electricity that can kill you, have an electrician check it out.

On TDY near Torey UT near ut12, my all time favorite road.

Don't most converters have a fuse on their output line? Also, regardless of whether the converter does or doesn't have power or deliver battery charging, isn't the coach battery typically hardwired to the 12V distribution panel?

My thinking was that the 12 volt circuits are disconnected from the battery if shore power is supplied. Could very well be wrong, there is precedent for that. Just don't tell my DW.

Actually some vintage single stage converter/chargers required a battery at its DC output to reduce AC ripple and in some cases, battery separation could make the converter/charger output voltage unstable. That's no longer the case with current designs and the converter will support the 12VDC fuse panel even with the battery disconnected although obviously it will not supply any recharging to the battery. What I don't understand is how your plugging into shore power effectively separates the battery from the DC fuse panel. What is the model of the converter/charger?

My response was somewhat conjecture as who knows what is there. I'll delete the post to eliminate confusion.
