Hi,since purchasing our Sunseeker in September we have always kept in plugged in to shore power. We took it out a couple of times to state parks that were close and we used shore power there.
Now we have left for our tour of the U.S. and as long as we are plugged in everything is fine. Note we had never left the RV unplugged when not in use.
Upon arriving in Utah day before yesterday at my in-laws there was no place to plug in. We didnít leave anything on overnight. I went out yesterday morning and the coach batteries were completely dead. I cranked up the engine and that allowed me to crank the generator which allowed me to run the lights and stuff.
After running the generator less than 5 minutes and turning it off, the batteries showed charged on the gauge and I know that couldnít have charged up to full that fast.
What do you think I need to check first? Could the batteries have gone bad by being plugged into shore power all the time and not used or cycled? Or could something else be wrong?
Thanks in advance.
