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...

Had a chance to do some testing today. I have a Craftsman true RMS clamp meter so I wanted to see what the hertz was doing. Started up the genset and at first no flicker. With no load the voltage was pretty stable at 122V and would fluctuate maybe +/- 1V and the Hz was 62 to 63 Hz. Turned on a handful of lights, and started the refridgerator and one heat pump. Still no flicker for a while but then the lights started to flicker. While they were flickering, I measured 119 to 122V and 59 to 61Hz. Then the flicker stopped. The 12V breaker (50A) had flipped, so I reset it. Flicker stopped before I could get any more readings and never flickered again. Genset just purred like a kitten.
