Electrical Gremlins
The strong winds that had been hammering northern Indiana Friday continued all night long, and continued through much of yesterday. There was no question about it; we were not getting out on the highway. We really, really wanted to be on the go, but we really, really didn’t want to be blown all over the road and waste a bunch of fuel fighting the wind.
So we spent the day listening to music, cruising the internet and hoping that today would bring us better weather. About noon, our friend Michele Henry from Phoenix Commercial Paint stopped by to visit, and later on we went to dinner with Greg and Jan White. We all got a laugh about the fact that this was our third “farewell dinner” in as many days.
Back at Elkhart Campground, I spent some time studying our planned route, while Miss Terry decided to try making a batch of pumpkin cheese bread in her convection oven. This would only be her second attempt at baking in the oven, as she transitions from the gas oven we had in our bus conversion.
While Terry was using her electric mixer to blend the ingredients, we suddenly lost all electrical power in the motorhome. The Progressive Industries Electrical Management System (EMS) unit I got from Lawrence RV Accessories was showing 125 volts of power coming in. I pushed the button to turn our inverter on so we had power again from the inverter and battery bank, but the battery charger was not working.
I flipped all of the breakers on and off, went out to the campground’s electrical pedestal and flipped the breaker there off and on, but we still were not getting any shore power, just the inverter feed. If I turned off the inverter, we went dead again, though the EMS still showed incoming AC power.
Having exhausted my small store of knowledge, I called Greg and he came over. We ran through all of the things I had done already, and then Greg had me turn on our Onan generator. Still no power to the inverter, except what it was drawing from the battery bank. We both agreed that the problem might well be a blown transfer switch, which automatically switched between shore power and generator power.
After studying the books that came with our motorhome, I logged onto Winnebago’s website, where owners can download electrical and plumbing schematic drawings, along with paint codes and a ton of other valuable resource information for anything Winnebago has ever built.
With still no luck solving the problem at that point, Greg checked our inverter and pressed the reset button for the incoming breaker on it, and suddenly we had AC power again!
Apparently all incoming shore power is routed through the inverter, which really doesn’t make any sense to me, because if the inverter goes bad, we’d be stuck with no power to the motorhome at all. The way I wired our bus, the inverter was a supplementary power source, and taking it out of the line would not disrupt power to the coach. But we have to learn all about living in a factory made unit again, including engineering designs that boggle the mind.
With power restored, Miss Terry finished making her pumpkin bread, and it came out looking great. She is her own worst critic, but even she said it was pretty darned good! I thought it was delicious!
While I was enjoying a slice of yummy hot pumpkin bread, Bad Nick was busy with a new Bad Nick Blog post titled A Campaign Ad I’d Like To See. Check it out and leave a comment.
