working down in Bara, Mexico with no where to get it fixed. I took it apart and found out that the 12 volt muffin fan had failed and it wouldn't cool itself. I replaced it with one off the shelf I was able to find in town and it has worked ever sense. Knock on wood! It's been on board 7 or 8 years, 3 years cruising and the rest living aboard so it gets a bunch of use as a charger. We usually use the generator so not much time on the inverter portion but all and all, it's done pretty well. With all the bad press, if it does tank, I'll buy something else.
