Yes, this is a black wire that goes into the ceiling and I assume that it goes to the converter. I can't see inside the converter but I will remove it this weekend and see what I find.
The other day when this was happening I did measure the voltage of the battery and it was about 7.5 volts DC. So that might be the issue with drawing more amps because its low. I have had this battery for 2 years now but I didn't maintain it over the winter last year. I will remove the battery and have someone test it to see if there are issues with it. Then try to get a trickle charger and see if this happens again with a full charge on it.
