I have a  60 amp Progressive Dynamics power converter in my trailer.  It has a rocker switch that has transformer and battery.  It has 2 reset buttons all on the bottom.  I have a new marine battery this year.  Now, I can't run the 12v off the battery itself.  I assume I have to turn the switch to battery.  I have not pulled the battery out to check the charge yet.  I have also had an issue once or twice with my water pump running on landline and kicking out the reset on the converter.  If the battery is not charged after I leave it plugged in for a couple days what do I look for next?  While on a weekend campover some campers had a power surge.  I did not notice anything different when I got back to camp but the next campover is when I started having an issue.
