Generator voltage and 12V system fluctuations
Recently noticed the 12V lights flickering in our 2003 Dolphin. Used this as an excuse to upgrade the converter to a Boondocker 4 stage unit thinking our old Magnetek was going out. Also replaced ou...

OK. Great suggestions, but I am at the limits of my electrical abilities.
Chris - you are correct....it is a 1" sq. by 1/2" thick type with a small black reset button on the side mounted on the back of a large printed circuit board. It receives the 12V output from the convertor.
MexicoWanderer - good suggestions. You all have helped me decide to have my RV service dealer chase this down from here rather than the Cummins/Onan people. I think something on the 12V side is getting ready to fail and not so much just a generator output issue. If it was generator, I think the Cummins service center would have figured it out in the 2 hours they ran the generator and could not find anything. And I had the now 14 year old generator fully serviced by them, complete with new brushes at 1000 hours three years ago and the generator has 1300 hours now.
It just seems to me that it is something on the low voltage side, and perhaps the resettable 50A breaker that is getting ready to fail and just not there yet. By the way, I have touched this breaker several times during all of this and it does not run hot or even warm to the touch.
Thanks again for all the input and I will reply with what we find out or if we add the capacitor.
