Just wanted to thank everyone here for the "battery charger guidance". We arrived Saturday afternoon at the track and after starting the generator, I plugged in my battery charger, set it on a 15amp charge, hooked it straight to the battery, and it ran like that until late Sunday afternoon. Everything worked like normal with the 12volt stuff.
Seems every trip we take, this Cyclone tries to let us down. But you guys saved the weekend for the family. We have our last race next weekend and we're gonna do the same setup. Then in November, it goes back to RV Outlet with a looooong list of failed parts to be repaired; the converter being at the top of that list.
Thanks again y'all.
